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 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:Zeolite capable of selective, specific and efficient capture of radioactive cesium in soil or a liquid containing soil, and a method of capturing cesium are provided. A material (7) for the synthesis of a magnetized Na-P1 zeolite composite is obtained by mixing an iron compound with any of: coal incineration ash or paper-making sludge incineration ash; a mixture prepared using coal incineration ash or paper-making sludge incineration ash and sodium aluminate and/or aluminum hydroxide to adjust the Si/Al ratio to 2 or less; or, a mixture prepared using multiple of water glass, sodium aluminate and an aluminum compound to adjust the Si/Al ratio to 2 or less. A magnetized Na-P1 zeolite composite (11) containing crystals of Na-P1 zeolite (5) and crystals of magnetite (9) is obtained by using a sodium hydroxide solution (3) to perform alkali treatment. After the magnetized Na-P1 zeolite composite (11) is mixed into the soil containing radioactive cesium or a liquid containing said soil, recovery is performed by magnetic separation.

标 题 :Process for separation and recovery of methyl chloride from vent streams containing isobutane
发明人：ZARCHY ANDREW S; MAURER RICHARD T; CHAO CHEN C
权利人:UOP INC
摘要:The present invention provides a process for the recovery of methyl chloride from a mixture thereof with isobutane. The process employs pressure swing adsorption with a size selective adsorbent having a pore opening of between about 3.7x3.7 Angstroms and about 4.9x5.7 Angstroms, such as zeolite A, clinoptilolite and mixtures thereof to selectively adsorb methyl chloride from vent streams comprising methyl chloride and isobutane and recovering a tail gas stream enriched in methyl chloride. The process may be used in applications such as treating the vent gas streams from the direct synthesis of methyl chlorosilanes. The process provides an economical route to recovering a valuable raw material in the process of making silicones and reduces the volume and methyl chloride content of the vent stream which is typically incinerated to avoid the release of halogenated hydrocarbons to the atmosphere.
