Abstract
A process for selectively converting adsorbable hydrocarbon feeds containing straight-chain and slightly branched-chain hydrocarbons to olefins by contacting the feeds with crystalline silicates.
Claims10
A process for producing olefins from normal paraffins, slightly branched paraffins, and mixtures thereof, comprising contacting a feed which comprises said paraffins with silicalite, and producing an effluent of greater olefin content than said feed.
A process for producing olefins from normal paraffins, slightly branched paraffins, and mixtures thereof, comprising contacting a feed which comprises said paraffins with a composition which is substantially free of hydrogenation activity comprising silicalite composited in a matrix which is substantially free of cracking activity, said contacting occurring at temperatures from about 285.degree. C. to 595.degree. C., pressures from subatmospheric to 205 bar, and hydrogen to hydrocarbon volume ratios from about 350 to 3650 liters hydrogen/liter hydrocarbon;
- and producing an effluent of greater olefin content than said feed, wherein said olefin content is at least 10 weight percent of converted feed.
