Experience in production of polymetallic reforming catalysts

Abstract

Attempts to determine the effect of nonuniformity of air flow on the activity and selectivity of the series KR polymetallic reforming catalyst. Reports that a number of modified KR catalysts have been developed and are being used successfully in the petroleum industry. Discusses the manufacturing technology for the new and more efficient compositions, and emphasizes the importance of calcination. Suggests the following measures to further improve the reforming catalysts: production of new catalyst KR-110, which is an improved analog of the KR-104A with a modified support; production of new versions of the support (A-70 and A-75); production of highpurity aluminium oxide; and preparation of catalysts based on such supports. Points out that a large part of the present reforming capacity is scheduled for changeover to polymetallic catalysts in the eleventh Five-Year Plan.
