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: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:The present disclosure provides a method of synthesizing an aluminosilicate molecular sieve by a crystal seed-assisted method, a natural aluminosilicate clay mineral treated and activated by an alkali is used as a crystal seed for synthesis of the aluminosilicate molecular sieve, and the target molecular sieve product is synthesized by hydrothermal crystallization, wherein the synthesis process does not require addition of conventional crystal seeds of a molecular sieve or use of any organic template agent, thus the synthesized product does not require a calcination process to remove the template agent. The method of synthesizing an aluminosilicate molecular sieve by a crystal seed-assisted method can meet the requirements of both crystallinity and nucleation time, and greatly reduce costs of synthesizing the aluminosilicate molecular sieve, and reduce the environmental pollution caused by removal of the template agent by calcinating.

摘要:The invention relates to a multi-stage process for the continuous, phosgene-free preparation of (cyclo)aliphatic diisocyanates that comprises the conversion of (cyclo)aliphatic diamines into the corresponding (cyclo)alkylene biscarbamates and the thermal cleaving of the latter into the (cyclo)alkylene diisocyanates and alcohol. The urea used in accordance with the invention and also the urea employed for the preparation of urea equivalents (e.g. alkyl carbonates, alkyl carbamates) as a possible precursor for the synthesis of the (cyclo)aliphatic biscarbamates is unconditioned.
