EFFECT OF PORE VOLUME ON CRACKING PERFORMANCE OF RFCC CATALYST

Abstract

Abstract: X-ray diffraction (XRD), N2 physical adsorption, infrared spectra of pyridine (Py-IR), mercury intrusion porosimetry (MIP), field emission scanning electron microscopy (FE-SEM) and an advanced cracking evaluation (ACE) equipment were used to study the physicochemical properties and cracking performance of the RFCC catalysts with different pore volume. The results showed that the catalyst Cat-1 with pore volume of 0.46cm3/g has a conversion rate 6.86% higher than that of the catalyst Cat-2 with pore volume of 0.36cm3/g. The yields of LPG and C5+ gasoline increase remarkably and the selectivity of by-product (coke and dry gas) declines at reaction conditions of 530℃ and catalyst/oil ratio 5.

Key words: FCC, catalyst, pore volume, cracking performance
