摘要： A method for starting up a fixed bed propylene hydration reactor containing shape selective metallosilicate catalyst particles for the production of isopropanol and/or diisopropyl ether is disclosed comprising the following sequential steps: contacting a feedstream comprising propane with catalyst particles in a hydration reactor; then introducing a feedstream comprising isopropanol into the reactor to displace propane. Next, a feedstream comprising propylene is introduced into the reactor under etherification conditions. Finally, a feedstream is introduced in the reactor comprising water under etherification and hydration reaction conditions whereby diisopropyl ether and isopropanol are produced.

摘要： Olefins undergo conversion in the presence of water and recycled alcohol to a mixture of alcohol and ether which is then subjected to various downstream operations including distillation and extraction or decantation to provide an ether-rich product containing little if any alcohol or water. The foregoing process is especially suitable to the conversion of propylene and propylene-containing streams to diisopropyl ether which is useful, inter alia, as an octane improver for gasoline.

摘要： A process is disclosed for upgrading C.sub.5 -C.sub.8 olefin-containing gasoline to a high octane motor gasoline blending component.C.sub.3 -C.sub.4 olefins are hydrated to alcohols and then selectively removed from the aqueous hydration reactor effluent stream via liquid extraction with the gasoline feedstream. The alcohol enriched gasoline extract stream is then etherified and unreacted alcohols are extracted to yield a high octane gasoline blending component free of metal-bearing additives.

摘要： Light olefin is introduced at multiple points of entry into a conversion unit subdivided into first and second reaction zones. Reaction of olefin with water takes place in the first reaction zone under conditions intended to promote the production of alcohol therein and in the second reaction zone, alcohol produced in the first reaction zone is both dehydrated and reacted with olefin under conditions intended to promote the production of ether therein. The same or different shape selective acidic zeolites are employed as catalysts in both reaction zones.

摘要： This is a process for upgrading a petroleum naphtha fraction. The naphtha is subjected to reforming and the reformate is cascaded to a benzene and toluene synthesis zone over a benzene and toluene synthesis catalyst comprising a molecular sieve of low acid activity. The preferred molecular sieve is steamed ZSM-5. The benzene and toluene synthesis zone is operated under conditions compatible with the conditions of the reformer such as pressures of above about 50 psig (446 kPa) and temperatures above about 800.degree. F. (427.degree. C). In one aspect of the invention, the benzene and toluene synthesis catalyst includes a metal hydrogenation component such as cobalt, nickel, platinum or palladium. In one mode of operation, the benzene and toluene synthesis catalyst replaces at least a portion of the catalyst of the reformer. The process produces a product containing an increased proportion of benzene and toluene, and a reduced proportion of C8 aromatics, particularly ethylbenzenes, as compared to the reformate.
