摘要： This invention relates to a process for restructuring an olefinic feedstock rich in linear olefins into a product olefin of narrower composition which is richer in branched olefins than the starting feedstock. Such restructuring is achieved by contacting the feedstock with an unmodified or partially modified tectometallosilicate of the Theta-1 type at relatively low temperatures. The product olefins are valuable as petrochemical feedstock for producing polyolefins, alcohols, ethers and other oxygenates, surfactants, alkyl aromatics and oligomers useful as gasoline blending components.

摘要： A catalyst which comprises zinc, together with an effective amount of a platinum group metal on a support which is a material having the silicalite structure, the framework of said material consisting essentially of silicon and oxygen atoms or of silicon, zinc and oxygen atoms. There is also provided a process for the dehydrogenation of a C.sub.2 to C.sub.10 paraffin to yield an alkene product which process comprises contacting the paraffin under dehydrogenation conditions with a catalyst according to the invention.
