Hydrogen oriented underground coal gasification for Europe

(O. Solcova, supported by Research Fund for Coal and Steel (RFCS), project No. RFCR-CT-2007-00006)

The project explores the technology for hydrogen production through underground gasification of coal in a dynamic geo-reactor. The process is controlled through purposed dynamic changes in temperature and pressure of the reactants and products. The project addresses CBM usage and CO2 sequestration in coal deposits. The environmental fingerprint of the technology on air, water and strata stability is evaluated. The locations of demonstration plants are chosen through computer modelling and simulation. Large scale production of hydrogen from coal is crucial for coal mining industries and will serve the needs of energy, chemistry and transportation sectors of Europe. [Refs. 39-40, 52, 67, 95-97]

Hierarchic nanosystems for microelectronics

(O. Solcova, joint project with JH IPC, IMC, Institute of Microbiology of the ASCR, v.v.i., Institute of Physics of the ASCR, v.v.i., ICT, CU, UJEP, and Research Institute of Organic Syntheses Pardubice, supported by ASCR, project No. KAN400720701)

Project develops the complex composite systems with precisely defined performance applicable in microelectronics. The individual components will be formed by small arranged particles which will ensure partial function inevitable for functioning of the whole system. These composite structures should be directly applicable as elements of special sensors, photoelectric energy sources, microelectrodes for analytic instruments etc. The general aim of the project is the accumulation of sufficient amount of high-quality experimental data to be applied for design and implementation of practical nanotechnologies. Professionally, the project is focused on the study of preparation of hierarchic nanostructures, inclusive the structural and functional characterization, as well as on prediction of properties by means of mathematical modeling. [Refs. 7-10, 12, 20, 33, 43-45, 50-51, 63-65, 73-76, 90-94, 98]

Diffusion coefficients and other transport characteristics of specially shaped porous supports and catalysts

O. Solcova, supported by ASCR, grant No. IAA4072404)

The project develops and verifies a new method for the determination of diffusion coefficients and other transport characteristics of industrial porous solids with non-standard shapes (which guarantee high outer surface to volume ratio). The chromatographic method in SPSC arrangement has been applied. To decrease the number of fitted parameters, the axial dispersion parameter (Peclet number) has been obtained independently of responses of SPSC packed with porous pellets with pores blocked by a suitable liquid - Porofil (nonporous packing). The obtained diffusion coefficients and other transport characteristics have been compared with characteristics from standard textural analyses. [Refs. 21-22, 42, 46, 66, 86-88, 99, 101]

Porous catalysts and membrane supports: a relationship between mass transport and textural properties

(V. Hejtmanek, supported by GACR, grant No. GA203/05/0347)

The objective of this project is a modern approach to characterization of catalyst and membrane support pore structures and the investigation of a relationship between mass transport and pore structure. The pore structure characterization (reconstruction of pore space) of macroporous solids is namely accomplished by the generation of 3D image from many serial 2D cuts of actual porous media. The reconstructed pore space serves as the key information for the development of a 3D random pore network model, which allows study of a more rational prediction of mass transport phenomena in porous solids. The application of the project results in heterogeneous catalysis, separation processes, and development of new catalysts is of primary interest. [Refs. 2, 31-32, 36]

Study of factors influencing the activity and selectivity of supported bimetallic transition metal sulfides in HDS and HDN reactions

(Z. Vit, supported by GACR, grant No. GA104/06/0870)

Pt/MSA a Pt-Mo/MSA catalysts based on mesoporous silica-alumina (MSA) synthesized by us were studied in simultaneous HDS of thiophene and HDN of pyridine. Monometallic Pt/MSA (up to 2 % Pt) was great at HDS while the promoted Pt-Mo/MSA (0.5 % Pt) showed high HDN. In contrast to alumina, MSA gave more active catalysts due to larger BET area and acidity. Other mesoporous materials such as carriers of Ni phosphide (SBA-15) and Mo, CoMo and NiMo phases (mesoporous alumina) were studied in HDS and HDN of other compounds too, such as benzo- and dibenzothiophene and o-methylaniline. Inhibition of HDS of thiophene by pyridine was studied with Rh-Mo, Ru-Mo and Pd-Mo/alumina and CoMo a NiMo catalysts. Catalysts promoted by noble metals were more resistant to the inhibition than conventional ones and in the presence of pyridine; they were more active in HDS than CoMo. [Refs. 11, 29, 41, 56, 57, 100]

Synergistic effects in hydrodesulfurization and oxidation reactions

(K. Jiratova, bilateral co-operation with Institute of Catalysis, Sofia, Bulgaria)

CoMo/Al2O3 catalyst prepared by impregnation of alumina support with cobalt heteropolyoxomolybdate was tested in hydrodesulfurization (HDS) of thiophene, 1-benzothiophene, or light gas oil) under various reaction conditions and reactor arrangements. Its physicochemical properties are also examined. The obtained data are compared with those of two industrial HDS catalysts. [Refs. 23, 89]

Deposition of oxide catalysts for oxidation of VOC onto preformed support and their modification by nanoparticles of noble metals

(K. Jiratova, joint project with ICT, and IIC, supported by GACR, grant No. GA104/07/1400)

Mode of the promoters (Pt, Pd, La, Ce, K, Li) incorporation into Co4MnAl oxidation catalyst and its effect on the activity and selectivity in total oxidation of model VOC (toluene, ethanol) was studied. Addition of potassium showed the highest positive effect on catalyst activity, as it modifies acid-base properties of the catalysts. The effect of LDH precursor crystallinity was studied over the Ni4Al2 system. The highest catalytic activity was found with the system not having too high crystallinity. Formation of LDH precursors on oxidized Al foil under hydrothermal conditions was also studied. [Refs. 13, 28, 31, 35, 36, 58, 78-80]

Unconventional supports in catalysis over sulfides

(M. Zdrazil, supported by GACR, grant No. GA104/06/0705)

MoO3/TiO2 catalysts were prepared by conventional impregnation of TiO2 supports with surface areas of 140, 230, and 407 m² g^-1. The loading of MoO3 was 2-32 mass%. According to the point of zero charge, the supports were saturated with a molybdena monolayer at approximately 12, 24 and 14 mass%, respectively. Activity in hydrodesulfurization of thiophene increased up to the loading of ~20 mass% and then decreased for all three supports. [Refs. 4, 54]

Preparation of supported catalysts by slurry impregnation

(L. Kaluza, supported by GACR, grant No. GP104/06/P034)

The shaped supports Al2O3, ZrO2 a ZrO(OH)2 were successfully impregnated by slurry MoO3/H2O to prepare sharp eggshell concentration profile of Mo, the thickness of which was simply regulated by the nominal amount of MoO3. The slurry impregnation thus represented a simple and clear method of the preparation of hydrodesulfurization catalysts, which does not insert NO3(-) and NH4(+) ions into the system, need calcination of catalysts, and distilled water (methanol) evolved during is the only by-product. The highest activities in benzothiophene hydrodesulfurization were obtained after deposition of the promoters (Co, Ni) onto pre-sulfided monolayer Mo catalysts from acetylacetonate precursors. It was found that the monoclinic ZrO2 (baddeleyite) and tetragonal TiO2 (anatase) significantly and systematically increase hydrodesulfurization activity of sulfided V, Cr, Mn, Fe, Co, Ni, Mo, Ru, W, and Os species in comparison to conventional Al2O3 support while the activity of sulfided Rh, Pd, Ir, Pt and Re is not influence or is decreased. [Refs. 5-6, 23, 32, 59-62, 89]

Chemical structures from the analysis of pair density and related quantities

(R. Ponec, supported by ASCR, grant No. IAA4072403)

The project is a part of longer-term efforts at the systematic exploitation of the pair density as new source of the information about the molecular structure and nature of chemical bond. This density represents the basic theoretical quantity allowing us to describe the behaviour of electron pairs in microscopic systems. In the past several years it was proven to provide new valuable insights into the role of electron pairing in chemical bond. Especially useful in this respect were found the approaches known as the analysis of domain averaged Fermi holes and the generalized population analysis. These approaches have been applied to the interpretation of the bonding in molecules with complicated bonding pattern like metal-metal bonding, 3-center 4-electron bonding, hypervalence, etc. and to the quantitative characterization of the extended cyclic delocalization in aromatic hydrocarbons. [Refs. 2, 16-19, 25, 27, 38, 85]

Advanced catalytic processes and materials

(J. Hanika, O. Solcova, joint project with JH IPC, ICT, CU, and UPa, supported by GA CR, grant No. GD203/08/H032)

The concerted project is aimed at a development of new selective catalytic and separation processes for preparation of specialty compounds and materials, which can give rise to a progression in the field of new chemical technologies. The processes in question are stereoselective and regioselective transformations on chiral catalytic centres and processes with significant environmental impact. Coordination of Thesis projects is planned in the field of catalysis, e.g., developed Rh catalysts can be tested in stereospecific polymerizations (CU), asymmetric synthesis (ICT) and hydrocarbonylations; oxidation catalysts can be tested in organic synthesis (ICT, UPa, ICPF), oxidation polymerization (CU) and synthesis of chemical specialties (JH IPC); new mesoporous materials prepared at JH IPC will be used in all other partner laboratories, etc. [Refs. 24, 68-72, 82]
