Sulphur reduction catalyst additive composition in fluid catalytic cracking and method of preparation thereof

摘要

The present invention relates to sulphur reduction catalyst additive composition comprising an inorganic porous support incorporated with metals; an alumino silicate or zeolite component; an alumina component and clay. More particularly the present invention relates to sulphur reduction catalyst additive composition comprising refinery spent catalyst as support. The primary sulphur reduction catalyst additive component of the catalyst composition contains metals of Period III or IV of the Periodic Table, preferably Zinc or Magnesium or combination thereof or one of the transition metals along with other metals. 0 20 40 60 80 100 120 140 pore size, A Fig. 1 Pore size distribution of spent refinery catalyst support material
