The FCC process is of major importance in modern refineries and the optimum performance of the unit has a marked effect on overall refinery economics. To meet refiners demand for improved selectivity and metals tolerance developments in cracking catalyst technology have accelerated over the last 3 years. In addition, physical properties, such as attrition resistance, particle size distribution and fluidisation characteristics have now to be controlled and optimised in order to maximise unit performance. The fluid cracking catalyst has three main functions in a FCCU: - to supply active acid sites to the reactor, to crack the feedstock; to contain the effect of contaminants, such as nickel and vanadium etc.; to transfer the necessary heat from the regenerator to the reactor system. The catalytic effect in a unit is evident in two ways: - by altering catalytic coke production and by modifying liquid selectivities.
