CATALYTIC DEWAXING OF AN INTER NEUTRAL RAFFINATE OVER NI-IMPREGNATED HZSM-5
Dewaxing of an inter neutral raffinate has been studied over HZSM-5 (SiO2/Al2O3 ratio 80) impregnated with nickel in a high pressure, fixed bed reactor under varying conditions of temperature, pressure and feed now rate. The zeolite is bound in an alumina matrix (zeolite to alumina ratio 65:35 w/w). The feed, which has a pour point of 313K, shows a vast improvement in fluidity characteristics after dewaxing. The pour point is found to be dependent on the reaction temperature and decreases to 249 K with reaction temperature increasing to 596 K.
