Processes for chemical conversion of volatile organic compounds to value added products using membrane reactors and recovery of one or more purified conversion product are described. Useful membranes are preselected to control the relative amount of noncondensable co-product in gaseous reactor effluent such that the energy required for the subsequent compression and partial condensation of the reactor effluent is reduced.

Processes using heterogeneous adsorbents are disclosed for purification of olefin streams, such as are produced by thermal cracking of hydrocarbons, to obtain a feedstock suitable for formation of olefin polymers. These purification processes comprises: providing an impure gaseous mixture; passing the impure mixture through a bed of regenerated adsorbent which is free of a substantial amount of carbon monoxide; effecting, in the presence of an essentially dihydrogen-free atmosphere within the bed, selective adsorption of the contained acetylenic impurities with the adsorbent until levels of the acetylenic impurities in the effluent mixture increase to a limiting level in a range downward from about 1 parts per million by volume; and thereafter regenerating the resulting bed of adsorbent in the presence of a reducing gas comprising dihydrogen which reducing gas is free of a substantial amount of carbon monoxide.

Processes using heterogeneous adsorbents are disclosed for purification of olefins to obtain feedstocks suitable for formation of olefin polymers using a metallocene catalyst system. An olefinic process stream, containing small amounts of acetylenic impurities, carbon oxides and/or other organic components which are, typically, impurities in cracked gas, passes through at least two zones containing heterogeneous adsorbents. Adsorption is carried out in an essentially dihydrogen-free atmosphere within the initial zone containing a bed of regenerated adsorbent which has retained a substantial amount of carbon monoxide, to effect selective adsorption of the contained acetylenic contaminants with the adsorbent. An effluent mixture which contains less than about 1 part per million by volume of the acetylenic impurities and an amount of carbon monoxide deleterious to a metallocene catalyst system in formation of olefin polymers is contacted in a second zone with an adsorbent capable of effecting selective adsorption of the contained carbon monoxide, thereby obtaining a feedstock which contains less than about 5 parts per million by volume of carbon monoxide and less than about 1 parts per million by volume of the acetylenic impurities. Advantageously, the loaded bed of adsorbent in the first zone is regenerated in the presence of a reducing gas comprising dihydrogen and containing at least 50 parts per million of carbon monoxide, to effect release of the contained acetylenic impurities from the adsorbent.
