We have attempted a green alternative to reuse the spent fluid catalytic cracking (FCC) catalyst that is used in petroleum refining industry for the upgradation and purification of various petroleum streams and residues. The spent FCC zeolite–based catalyst modified by enhancing the acidic properties by incorporating Zn and In metals in the matrix. The various prepared catalysts were systematically characterized by X-ray powder diffraction and Brunauer–Emmett–Teller (BET; adsorption isotherm) surface area. The acidity of the materials was studied by temperature-programmed desorption of ammonia (NH3-TPD). The well-characterized catalysts were applied for liquid phase benzylation of o-xylene using benzyl chloride.

Vanadium and nickel were found as major contaminants on spent FCC catalyst at levels of 3518 ppm and 3225 ppm, respectively. XPS results indicated that vanadium and nickel were in oxide form on spent FCC catalysts. Leaching tests (TCLP) showed that vanadium from spent FCC catalysts poses an environmental problem if disposed by landfill. It was found that encapsulation treatment with up to 60 wt % spent FCC catalyst in Portland cement, is an effective means of stabilization. The strength of standard specimens containing catalyst was much lower than that of standard specimens made with same weight percentage of sand.
