摘要：Deactivation of a Pd/HM hydroisomerization catalyst is described. Catalyst deterioration during elimination of coke by combustion was examined. The main cause was sintering of loaded palladium particles on Pd/HM catalysts. It was noted that not only the amount but also properties and place of coke deposits can have a dramatic effect on restoration of catalytic performance. Optimum temperatures were in the range of 530-550 degrees C for ex-situ regeneration by oxidative burnoff of coke.
