Catalytc cracking of palm oil to gasoline using zeolite catalysts

The refined, bleached and deodorized palm oil (RBDPO) was converted to gasoline by passing its vapor through catalyst in a fixed bed reactor at atmospheric pressure. The resulting gas and liquid products were analyzed with a gas chromatograph. The catalysts were characterized with X-ray diffraction...
