    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.
