Abstract:
A method for the separation of hydrocarbon compounds utilizing a dividing wall distillation column is described. The dividing wall distillation column enables one or more side draw stream to be removed from the dividing wall distillation column in addition to an overhead stream and a bottoms stream.

Abstract:
A bulk metal oxide catalyst can be prepared by combining metal oxide powders or oxide-producing species and reacting selected ingredients prior to their inclusion in the formulation of the catalyst. Mixed metal oxide phases can be designed and prepared for use as an ingredient for a bulk metal oxide catalyst to alter properties for catalytic performance or physical properties that would not be obtained using mixtures of singular metal oxide ingredients.
Abstract:
A catalyst includes a metathesis catalyst and an isomerization catalyst. In one embodiment, WO3 is supported on MgO. Alternate embodiments include an inert support, such as alumina or silica, where either one or both of WO3 and MgO are supported on said inert support. The metathesis catalyst can be used for the metathesis of olefins, such as the metathesis of 2-butene and ethylene to produce propylene.
Abstract:
A method of producing an alkylaromatic by the alkylation of an aromatic with an alkylating agent, such as producing ethylbenzene by an alkylation reaction of benzene, is disclosed. The method includes using an H-beta catalyst to minimize process upsets due to alkylation catalyst deactivation and the resulting catalyst regeneration or replacement. The H-beta catalyst can be used in a preliminary alkylation reactor that is located upstream of the primary alkylation reactor. The H-beta catalyst used in a preliminary alkylation reactor can lead to the reactivation of the catalyst in the primary alkylation reactor.

Abstract:
A process for the coupling of hydrocarbons and utilizing the heat energy produced by the reaction is disclosed. In one embodiment the process can include reacting methane with oxygen to form a product stream containing ethane and further processing the ethane to ethylene in an existing ethylene production facility while using the heat energy produced by the reaction within the facility.
