摘要： Generally, regenerable, encapsulated metal oxide catalysts comprising a ceramic matrix and metal catalysts may be used to convert alkanes to alkenes. The encapsulated metal oxide catalyst may be tailored to produce a variety of alkenes including ethylene, butylene, and propylene. Further, the encapsulated metal oxide catalysts advantageously allow for regeneration and reactant recovery for cost effective and environmentally friendly processes.

摘要： The invention relates to a process for producing alkylated aromatic hydrocarbons comprising the steps of: (a) subjecting a mixed hydrocarbon feedstream comprising benzene to a separation to provide a C6 cut comprising benzene, wherein the C6 cut comprises at least 60 wt-% of C6 hydrocarbons; (b) subjecting the C6 cut to catalytic cracking or thermal cracking to provide a cracking product stream comprising benzene and C2-C4 alkenes and (c) after step (b), without pre-separation of the cracking product stream, subjecting the cracking product stream to conditions suitable for alkylation to provide an alkylation product stream rich in alkylated aromatic hydrocarbons, wherein the process further comprises the steps of separating benzene and benzene coboilers from the alkylation product stream to obtain a stream of benzene and benzene coboilers and wherein the stream of benzene and benzene coboilers is separated into a benzene-rich stream comprising a higher proportion of benzene than the stream of benzene and benzene coboilers and a benzene-lean stream comprising a lower proportion of benzene than the stream of benzene and benzene coboilers and wherein the benzene-lean stream is recycled back to the catalytic cracking or thermal cracking in step (b).

摘要： A method for the efficient synthesis of useful deoxygenated terpenoids from an abundant renewable source, using catalytic conversion of oxygenated terpenoids. Oxygenated terpenoids such as 1,4-cineole and 1,8-cineole are, for example, major components of turpentine and essential oils. These oxygenated terpenoids can also be produced from sugars via a biosynthetic approach. Catalytic deoxygenation of these substrates can be used to efficiently generate commercially important chemicals and high density fuels for turbine or diesel propulsion.

摘要： A process for making high density fuels, pure terpene dimers, and byproducts from mixed terpene feedstocks and the resulting high density fuel products. The fuels produced by the process includes, dimerizing at least one terpene feedstock by mixing at least one terpene with at least one heterogeneous acidic catalyst and at least one solvent used to control the reaction temperature for a desired time and temperature to produce a crude terpene dimer (C20H32 mixture) in about 65% to about 95% chemical yield, hydrogenating the crude terpene dimer (C20H32 mixture) with at least one hydrogenation catalyst under a hydrogen atmosphere and removing the hydrogenating catalyst(s) to produce about 65% by weight to about 95% by weight of hydrogenated terpene dimer mixture, and utilizing a separation method against the hydrogenated terpene dimer mixture to produce byproducts, where the process generates a hydrocarbon mixture with a viscosity of between about 20 and 50 cSt at 40° C.
