The effe tw of rea tion temperature ( 240 e ~ 390 e ), - 1 - 1 pressure ( 2. 0M Pa~ 3. 0M Pa), vo lum e airspeed ( 1. 0 h ~ 2. 0 h ) and hydrogen o il volum e ratio ( 800B1~ 1200B1) w ere exam ined. Rea tion temperature has a rem arkable influen e on the rem oval rate of sulfur and n itrogen. Rea tion pressure does not show obvious mi pa t on the rem oval rate for light fra tion pyrolyti o i.l How ever, h igher rea tion pressure mi proves the removal rate for m iddle fra tion pyrolyti o il, espe ially den itrogenation rate. Low er volum e airspeed and h igher hydrogen oil volume ratio in rease the removal rate of both sulfur and nitrogen. The optmi um ond iti
