Isoalkane / n- alkane method of separation by adsorption in the gas phase using an adsorber of pressure change and the four

摘要

PROBLEM TO BE SOLVED: To provide a means reducing a floor size in a separation method by the adsorption of n-paraffin and isoparaffln in a gaseous phase from a hydro carbon charge raw material supplied from an isomerizing method. ;SOLUTION: N-paraffin and isoparaffin are separated by the adsorption of n-paraffin in a gaseous phase from a mixture of nparaffin and isoparaffin. In this method, four No.1-No.4 adsorbers are used and substantially same in size and act corresponding to at least one process cycle. A treated mixture is more specially obtained by isomerizing C₅/C₆ hydrocarbon.;COPYRIGHT: (C)1998,JPO
