Experience of commercial production and operation of new reforming catalysts PR -81 and SHPR-81
Abstract
New reforming catalysts PR-81 and SHPR-81 differing from its predecessors (PR-51 and PR-71) by increased mechanical strength (1,8–2,2 vs 1,2–1,5 kg/mm) were developed in IHCP SB RAS and put into commercial production. At «Angarsk plant catalysts and organic synthesis» by Rosneft Company a four parties of the catalysts total weight 78 tons are turned out for the three industrial reforming units, working on gasoline and aromatic scheme («Purneftepererabotka», «Gazprom Salavat Petrochemical», «GazpromNeft - Omsk Oil Refinery »). Comparative analysis of new catalysts and their predecessors was hold. It is shown that the catalyst PR- 81A which was used at commertial unit LP-35-11/40 in the period 2010–2013 is characterized by increased activity (the temperature for achieving the desired stiffness of the process on 25–30 °C lower than for the PR-71 catalyst) and the yield of the stable reformate to 2–3 wt.% higher and aromatics content on 5 wt.% lower. Combined loading of commercial unit L-35-11/600 by catalysts PR-81A/SHPR-81 provide a producing of gasoline with RON 95-97 even under adverse operating conditions and low quality of feed. The obtained results allow us to rely on the widespread introduction of new catalysts to refineries in Russia and CIS countries.
