摘要:In a process for preparing a high activity, large crystal ZSM-5 type zeolite in the absence of a template, a reaction mixture can be prepared comprising water, a silica source having a surface area less than 150 m 2 /g, an alumina source, seeds, a source of an oxide of an alkali metal, M, and a source of gluconic acid or salt thereof, Q, wherein the mixture has a SiO 2 /Al 2 O 3 molar ratio≦40. The reaction mixture can be heated to a crystallization temperature from about 100° C. to 200° C. for a time sufficient for crystals of ZSM-5 to form Crystals of ZSM-5 can then be recovered from the reaction mixture which crystals can have a SiO 2 /Al 2 O 3 molar ratio≦40 and a majority of which crystals can have at least one crystalline dimension of at least about 2 μm.

摘要:The present technology provides compositions, methods, and processes to form polysiloxanes. In one aspect, the present technology provides a process for the ring opening polymerization of a cyclosiloxane comprising contacting a cyclosiloxane with a bicyclic guanidine compound. The guanidine-containing compounds useful in the ring opening reaction include a fused ring structure comprising a guanidine functional group as part of the fused ring.

摘要:There is provided a catalyst containing porous macrostructures comprised of: (a) a three-dimensional network of particles of porous inorganic material (e.g., zeolites); and, (b) at least one metal (e.g., a catalytically active metal). The particles of the at least one macrostructure occupy less than 75% of the total volume of the at least one macrostructure and are jointed together to form a three-dimensional interconnected network. The three-dimensional interconnected network will usually be comprised of pores having diameters greater than about 20 Ã…. The macrostructures can be made by forming an admixture containing a porous organic ion exchanger (e.g., a polymer-based ion exchange resin) and a synthesis mixture (e.g., for zeolite formation) capable of forming the porous inorganic material and the at least one metal; converting the synthesis mixture to the porous inorganic material; and removing the porous organic ion exchanger from the inorganic material. The metal-containing macrostructures find application in hydrocarbon conversion (e.g., hydrogenation, dehydrogenation, dehydrocyclization, isomerization, hydrocracking, dewaxing, reforming, conversion of alkyl aromatics, etc.) and in the reduction of emissions of hydrocarbons, carbon monoxide, and/or oxides of nitrogen from an internal combustion engine.
