Abstract:
A porous crystalline material has a tetrahedral framework comprising a general structure, M'-IM-M 2 , wherein M 1 comprises a metal having a first valency, wherein M 2 comprises a metal having a second valency different from said first valency, and wherein IM is imidazolate or a substituted imidazolate linking moiety.
Abstract:
The present invention is directed at a process to isomerize C10+ hydrocarbon feedstreams by contacting a C10+ hydrocarbon feedstream with a steamed catalyst.
Abstract:
A method is provided for forming a zeolitic imidazolate framework composition using at least one reactant that is relatively insoluble in the reaction medium. Also provided herein is a material made according to the method, designated as EMM-19, and a method of using EMM-19 to adsorb gases, such as carbon dioxide.
Abstract:
A method is provided for replacing at least a portion of the organic linker content of a zeolitic imidazolate framework composition. The method comprises exchanging the organic linker with another organic linker. Also provided is a new material, designated as EMM-19, and a method of using EMM-19 to adsorb gases, such as carbon dioxide.
Abstract:
The present invention relates to engineered structured adsorbent contactors for use in pressure swing adsorption and thermal swing adsorption processes. Preferably, the contactors contain engineered and substantially parallel flow channels wherein 20 volume percent or less of the open pore volume of the contactor, excluding the flow channels, is in the mesopore and macropore range.
Abstract:
The management of hydrogen in hydrogen-containing streams associated with petrochemical process units wherein the hydrogen-containing stream is subjected rapid cycle pressure swing adsorption to increase the concentration of hydrogen therein.
Abstract:
This invention relates to a mesoporous catalytic cracking catalyst, a process for the production of such catalysts, and a process utilizing such catalysts in cracking operations. The mesoporous fluidized catalytic cracking catalyst is selective for minimizing the production of coke and light gas. The catalyst comprises an amorphous, porous matrix having pores ranging in diameter from 1 Å to 10 Å and ranging in diameter from 40 Å to 500 Å , but substantially free of pores ranging in diameter from 10 Å to 40 Å.
Abstract:
A process for converting feedstock triglycerides to lube basestocks. The process has the steps of (a) metathesizing the feedstock triglycerides with ethylene in the presence of a metathesis catalyst to form alpha olefins and medium-chain triglycerides and (b) hydroisomerizing the medium-chain triglycerides in the presence of a hydroisomerization catalyst and hydrogen to form methyl-branched triglycerides. The alpha olefins may be oligomerized in the presence of an oligomerization catalyst to form poly(alpha olefins).
