This article attempts to determine the resistance of KMTs-R commercial microbead catalyst to poisoning by heavy metals by preparing samples of this catalyst with various contents of nickel. The nickel was deposited by impregnating the catalysts with a benzene solution of nickel naphthenate at the appropriate concentration. It is determined that as the content of nickel in the catalysts is increased, the feedstock conversion, the naphtha yield, and the selectivity for naphtha dropped off monotonically. The effect of antimony diamyldithiocarbamate (compound I) on the poisoning of KMTs-R catalyst by nickel is examined. The results indicate that nickel on the catalyst is passivated by compound I. It is concluded that the parameters of nickel-poisoned KMTs-R catalyst can be restored to a great degree by treatment of the poisoned catalyst with compound I.
