    摘要： A hydrocarbon stream is cracked to produce a hot gaseous stream which is compressed and cooled to condense almost all of the hydrocarbons contained in the stream. A noncondensed stream remaining after the condensation step, comprised predominantly of hydrogen and C.sub.1 to C.sub.3 hydrocarbons, is subjected to pressure swing adsorption or temperature swing adsorption at an adsorption temperature of about 0.degree. to about 250.degree. C. in a bed of adsorbent which selectively adsorbs ethene and propene, thereby adsorbing substantially all of the ethene and propene from the gas stream. The ethene and/or propene is recovered upon bed regeneration. Higher alkenes are separated from alkanes by various methods.

    摘要： The present invention provides for a process of separating hydrocarbons such as short chain paraffins and olefins from non-hydrocarbon gases using short-cycle time concentration swing adsorption processes. The hydrocarbons are adsorbed from the gaseous stream on highly siliceous nanoporous materials, e.g., such as of aluminum-deficient faujasite-type zeolites, by way of a pressure, vacuum or temperature swing adsorption, then desorbed from the adsorbent in the presence of steam. Optionally, the steam is desorbed from the adsorbent through the use of air or inert gas or a recycle of the waste gas effluent. The invention also provides for a new method of preparing novel shapes such as beads and monolithic structures of the highly sileceous nanoporous materials.
