摘要： Separation of ethylene from ethane is achieved by feeding a mixture of the C2 hydrocarbons in contact with a CTS-1 crystalline titanium silicate molecular sieve which has a controlled pore size to selectively adsorb ethylene and size exclude ethane. The feed stream can also contain acetylene which can be selectively adsorbed from both ethane and ethylene by further controlling the pore size of the CTS-1 molecular sieve. Propane/propylene separation is also disclosed.

摘要： This invention relates to zeolitic molecular sieve compositions and hybrid zeolite-silica compositions characterized by novel morphology in which the zeolite is present as macroscopic aggregates of microcrystalline zeolite. The zeolitic compositions of this invention have outstanding capability to complex multivalent cations, especially calcium due to the high exchange kinetics of the microcrystalline zeolite component and yet have the ease of handling due to the macroscopic aggregate assemblage.

摘要： Aluminosilicate zeolites are formed in a novel reaction medium which contains a silicate source and an aluminum source in an aqueous alkaline solution and which reaction medium further includes an additional electrolyte salt. The addition of the electrolyte salt provides nucleation sites for the zeolite so as to form very small crystals. In high silica reaction environments, it is possible to form high aluminum zeolites which contain occluded silicate and wherein the morphology of the zeolites comprise macroscopic aggregates of microcrystalline zeolites. The addition of the electrolyte salt can also decrease the reaction time or temperature needed for crystallization.
