Experience in using PR-50 and PR-51 polymetallic reforming catalysts

In 1997 - 1979, Ryazan' Oil Refinery was the first in the industry to conve rt all reforming units to KR-102, KR-104, and KR-106 polymetallic catalysts . The individual stages of the process were perfected, which allowed improv ing the technical and economic indexes of operation of the units in compari son to the indexes for the monometallic AP-64 catalyst [1 - 3]. KR-108 and KR-110 catalysts, primarily distinguished by high selectivity, were used in three reforming units in 1982 - 1983 [4]. These catalysts were the most wi dely used in the industry and were successfully used to the beginning of th e 1990s [5].
