Abstract

A method is disclosed for reducing fouling in catalytic cracking. The method includes subjecting a recycled fossil-based feedstock to a heat treatment, evaporating the heat-treated feedstock, hydrotreating resulting evaporation distillate and performing catalytic cracking of the hydrotreated distillate in a presence of a solid acid catalyst.
