(487af) Increasing the Efficiency of Operating Plants IN Dehydrogenation of N-Paraffins

The study shows that the limiting parameter of the process taking place in the dehydrogenation reactor is the low coefficient of conversion of paraffins into monolefins.

The optimal operating parameters for the reactor have been found.

A kinetic model of the process was built to show its adequacy. On the model, the maximum conversion of paraffins was found with a constant selectivity of the diolefins. The profile of optimal reactor temperature was researched and two different temperature zones were found: one high, and one low.

It was shown that the optimal temperature conditions can be obtained by splitting the reactor into two sections. A two-stage process was suggested allowing the increase in production of monolefins by 15%, and reducing the recycling of paraffins by 20%, and keeping the same length of use of the catalyst.
