Synthesis of Active Matrix from Kaolin for Cracking Catalyst
Keywords:
active matrix, FCC, kaolin, silica-aluminaAbstract
The demand for fuel oil grows in tandem with population and economic development. The process of obtaining fuel from heavy-fraction feed is known as fluid catalytic cracking (FCC). Zeolite, active matrix, filler, and binder are the components of FCC catalysts. To pre-crack large feed, the active matrix is used. Matrix can be synthesized using kaolin. The purpose of this research is to obtain the best active-matrix variation with the optimum physical characteristic and acidity. The variations used were Si/Al = 6-14. The physical characteristics of the active matrix were characterized by nitrogen physisorption and the acidity by NH3-TPD. The findings revealed that the cracking conversion and product composition are depends on physical characteristic and the acidity of matrix. The best matrix variation is SA14 with Si/Al = 14 producing matrix with surface area of 88.43 m2/g, average pore diameter of 176.56 Å, pore volume of 0.39 cm3/g, acidity of 0.130 mmol NH3/g, and light cycle oil (LCO) acquisition of 18.78%-wt.
