still for fullstendig isomerisation of normal paraffinkolveten

摘要

A process for virtually complete isomerization of the normal paraffin hydrocarbons contained in a feed stream consisting essentially of mixed normal and non-normal hydrocarbons, wherein the feedstock is first passed through an isomerization reactor and the hydrocarbons in the effluent from the reactor are passed through an adsorption section wherein the normals are adsorbed and the non-normals passed out of the system as an isomerate product. The fresh feed is controllably flow blended with the variable desorption effluent from the adsorber beds containing desorption normals and hydrogen purge gas in order to provide a constant flow of combined feed to the isomerization reactor.
