Kg. Bhattacharyya et al., CATALYTIC DEWAXING OF AN INTER NEUTRAL RAFFINATE OVER NI-IMPREGNATED HZSM-5, INDIAN JOURNAL OF CHEMICAL TECHNOLOGY, 1(5), 1994, pp. 293-296
Dewaxing of an inter neutral raffinate has been studied over HZSM-5 (S
iO2/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 alumi
na 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 decrea
ses to 249 K with reaction temperature increasing to 596 K.
