Fluid Catalytic Cracking (FCC) catalysts are composites containing zeolite dispersed in an amorphous matrix. Preparation, characterization and evaluation of catalyst activities were carried out in this work. Catalyst properties have been performed by using X-ray diffractometer (XRD), X- ray fluorescent spectrometer (XRF) and Microactivity Testing Unit (MAT). Influence of different catalyst compositions on theirs activities were investigated using three types of Y zeolite: REY, REHY and SRY. They were mixed with different binders such as silica sol, alumina sol and psuedoboehmite, and different sources of clay. The catalysts were evaluated by using light cycle oil as a feedstock. Microactivity, yield of gasoline and coke were found to increase as the unit cell size of catalyst increased (REY>REHY>SRY). The microactivity of catalyst containing alumina in matrix is higher than that of containing silica in matrix.
