摘要:A method for synthesis of porous inorganic materials, preparation of a catalyst and catalytic cracking of petroleum hydrocarbons thereof includes processes for synthesis of porous inorganic materials and preparation of the catalytic cracking catalyst and catalytic cracking of petroleum hydrocarbons. The synthesis process is advantaged in low cost in raw materials; the porous inorganic material has various pore structures; and transitional metal used overcomes the defects of the catalytic properties. The porous inorganic material serving as the main active ingredient and containing crystalline aluminum silicate zeolite structures provides surface acidity required by the catalytic reaction. The surface acidity is flexibly adjusted. The hierarchical pore profile improves the accessibility of the active center of the zeolite structure and favors the reaction efficiency and benefits of the petroleum hydrocarbon cracking, and reduces the negative effects caused by diffusion limit. The catalyst containing the porous inorganic material has low manufacturing cost and better properties.

摘要:The invention relates to an improved catalyst for the synthesis of dimethyl carbonate by reacting methanol, carbon monoxide and oxygen in the gas phase and to the use thereof. The catalyst consists of a copper-containing zeolite produced by admixing one or more halide-free copper(II) compounds to a zeolite in a liquid medium, drying the zeolite modified by the admixture, and tempering at 400-900° C. under inert conditions, essentially retaining the crystallinity of the zeolite, said admixing being effected by means of a method selected from the group consisting of impregnation of the zeolite, ion exchange, precipitation of copper(II) hydroxide in the presence of the zeolite, and a combination of these methods. The catalyst shows high space-time yields, is constant over the period of operation and has no corrosive action.

摘要:A catalyst and process for synthesis of dimethyl ether from synthesis gas are disclosed. The catalyst and process allow dimethyl ether synthesis at low pressures (below 20 bars) at a conversion rate close to the expected equilibrium rate. The catalyst is a combination of a methanol synthesis catalyst with metal components comprising Cu, Zn, Al, Mn and Cs and a methanol dehydration catalyst, wherein the dehydration catalyst is a dehydration agent which allows optimum production of dimethyl ether.

摘要:Current industrial processes for the production of lactic acid are fermentative, using lactic bacteria which require large volumes and create large quantities of liquid residue which need to be treated. Chemical literature also describes the use of reaction systems with homogeneous catalysis, which also pose problems which in turn impact our costs, owing to the increased requirements in terms of the control of the process and the type of reactor necessary. Therefore, the process used thus far, carried out in hydrogenolysis, isomerisation and oxidation are defective, owing to the significant formation of sub-products, mainly pyruvic acid and acetic acid and the low yield of lactic acid. n Lactic acid can also be obtained by the chemical transformation of other sources other than starch, but which are also renewable. The present invention provides a oxidative process for the production of lactic acid, in which the reaction with pure oxygen or oxygen mixed with air takes place below 100° C. and under autogenous pressure, using a noble metal catalyst in a metal oxide. The process uses 1,2-propanediol as primary material, derived from the reaction of hydrogenolysis of the glycerine, and reaches yields of more than 70% of lactic acid and less than 30% in sub-products, pyruvic acid and acetol.

摘要:Indolines of the formula ##STR1## wherein R 1 is hydrogen or C 1 -C 4 alkyl and each of R 2 and R 3 independently of the other is hydrogen, C 1 -C 4 alkyl or phenyl, are prepared by cyclodehydrating a 2-(2'-aminophenyl)ethanol of formula ##STR2## wherein R 1 , R 2 and R 3 are as defined above, at 150°-350° C. in the presence of an amorphous aluminum silicate. n The indolines of the above formula are useful intermediates for the synthesis of plant protective agents.
