Abstract
A process for increasing a yield of an isomerization zone by removing at least a portion of the C6 cyclic hydrocarbons from a stream prior to it being passed into the isomerization zone. Additionally, disproportionation reaction selectivity is also increased, producing valuable C3 hydrocarbons and C4 hydrocarbons. Also, a higher ring opening conversion of C5 cyclic hydrocarbons is observed. The isomerization zone may have an average operating temperature of at least 176° C. and an outlet molar ratio of hydrogen to hydrocarbon feed in the isomerization zone is less than about 0.2.
