NEW CATALYTIC REFORMING PROCESS WITH RECYCLING OF THE UPSTREAM REDUCTION EFFLUENT OF THE FIRST REACTOR AND RECYCLING OF THE RECYCLING GAS TO THE LAST OR REACTOR (S) OF THE SERIES.

摘要

The present invention describes a regenerative gasoline reforming process characterized by the recycling of at least a portion of the effluent from the catalyst reduction zone to the inlet of the effluent charge exchanger, which allows the charge to be preheated. Another part that can be recycled at the top of the first reactor, and by recycling the gas from the recycle compressor at the head of the last or the penultimate reactor of the series. This arrangement significantly improves the reformat production and hydrogen balance of the unit.
