摘要： A process for production of diisopropyl ether by conversion of hydrocarbon feedstock containing propene, propane and C.sub.2 - light gas components, including the steps of: optionally, prefractionating fresh feedstock containing propene, propane and C.sub.2 - light gas components to provide a reactor feedstream rich in propene; contacting the feedstock and water in a catalytic reactor with acidic catalyst under olefin hydration and etherification conditions; and recovering from the catalytic reactor a liquid reactor effluent stream containing diisopropyl ether, isopropanol, water, unreacted propene, propane and C.sub.2 - light gas components. Improved operation is achieved by separating the liquid effluent stream in a vertical stripper column; recovering an overhead vapor stream containing propene, propane and C.sub.2 - light gas components from the stripper column; cooling the overhead vapor stream to provide a reflux stream rich in condensed propene and propane; removing the C.sub.2 - light gas components from condensed; recycling the reflux stream to an upper contact portion of the stripper column; and recovering a predominantly C3 recycle stream from the upper contact portion of the stripper column. Optionally, the C3 recycle stream may be passed to the to the prefractioning step for propene enrichment with fresh feedstock.

摘要： Hydrocarbon feedstreams are desulfurized using an alkali metal reagent, optionally in the presence of hydrogen. Improved control over reaction conditions can be achieved in part by controlling the particle size of the alkali metal salt and by using multiple desulfurization reactors. After separation of the spent alkali metal reagent, the resulting product can have suitable characteristics for pipeline transport and/or further refinery processing.

摘要： After desulfurizing a hydrocarbon feedstream using an alkali metal reagent, the hydrocarbon feedstream can include particles of spent alkali metal salts. The spent alkali metal salts can be separated from the hydrocarbon feedstream and regenerated to form an alkali metal reagent, such as a alkali hydroxide or alkali sulfide. The regeneration process can pass through an intermediate stage of forming an alkali carbonate by successive reactions with carbon dioxide and calcium oxide. The calcium oxide can also be regenerated.
