摘要： The present disclosure relates to an FCC additive composition for bottoms cracking. The FCC additive composition comprises an acidity enhanced modified clay; an acidity enhanced modified alumina; a binder; a phosphorous oxide and a boron oxide. The present disclosure further relates to a process for the preparation of the FCC additive composition. The FCC additive of the present disclosure is capable of cracking bottoms comprising large hydrocarbon molecules/heavy fuel oils. The FCC additive composition of the present disclosure enhances bottoms conversion and reduces formation of dry gas.
