Present invention relates to a process for production of isomerization catalyst, containing a base of zirconia, a binder based on alumina and/or silica at-least one component of Group VI of the periodic table in the form of their oxyanions, a hydrogenation/dehydrogenation component loaded on the base, at least one metal selected from the group consisting of Pt, Pd, Sn, Re or mixtures thereof, and an peptization agent, wherein the peptizing agent is an organic acid and polymers, which improve the physicochemical properties of the isomerization catalyst for the production of C4-C12 paraffin's.

Method for catalyst production for C5-C12 paraffins isomerization

An isomerization method consists of a deisobutanizer column receives feed comprising n-butane. The deisobutanizer column delivers its bottoms a portion to a reboiler and another portion along with hydrogen is routed to a isomerization reactor and the reactor effluent is returned to the column. A stabilizer which is integrated with the column, an overhead stream used as a reflux and bottoms containing an iso-butane-rich stream that is the iso-butane product stream. The column overhead effluent is routed to separator, which splits the hydrocarbons and effluent, where the hydrocarbons are routed to deisobutanizer column and effluent recycled to stabilizer, where the stabilizer separates the reactor effluent into product streams contains an iso-butane product stream, a n-butane product stream, and a lighter hydrocarbon product stream.
