摘要： Alkynes are selectively hydrogenated in alkene rich hydrocarbon feeds, such as 1,3-butadiene-rich C.sub.4 cuts, by passing the hydrocarbon feed at least partially in liquid phase over a palladium-based catalyst in the presence of hydrogen, preferably in trickle mode, followed by passing the effluent, at least partially in liquid phase preferably containing about 300-400 ppmw alkynes, over a copper-based catalyst in the presence of hydrogen thereby producing a hydrocarbon product of significantly reduced alkyne concentration.

摘要： A process for production of gasoline comprising oligomerizing a C.sub.2 -C.sub.6 olefin containing feedstock over an intermediate pore size siliceous crystalline molecular sieve catalyst. The catalyst may take the form of silicalite, halogen stabilized silicalite, or a zeolite. Water may be supplied to the oligomerization reaction. The product from the oligomerization reaction is then subjected to an etherification reaction in the presence of methanol over an acid cation exchange catalyst to provide a gasoline product of enhanced octane number.

摘要： A catalytic treatment process is disclosed, which is carried out under pressure, in the presence of water, and with a molecular sieve catalyst which is TEA-silicate or silicalite previously stabilized by halogenation. This process may be applied to the aromatization or to the isomerization of hydrocarbon feedstocks, and to the oligomerization of olefins. The conversion rate of the process is very stable as a function of time.
