The influence of feedstock property on operation in the FCC unit was studied to identify the cause leading to deteriorated products distribution related with increasingly heavier feedstock for the ARGG unit. In order to maximize the economic benefits of the ARGG unit a string of measures, including the modification of catalyst formulation, retention of high catalyst activity, application of mixed termination agents to control the reaction temperature and once-through operation, and optimization of catalyst regeneration technique, were adopted to adapt the ARGG unit to processing of the heavy feedstock with its carbon residue equating to 7% on an average. The heavy oil processing technology has brought about apparent economic benefits.
