This study a.ms to compa.e the pyrolysis beha.ior of Hua.ia. oil sha.e in two infra.ed hea.ing fixed bed rea.tors with different directions of infra.ed *** previous work ha. shown tha. fa.t pyrolysis of oil sha.e conducted in the sha.low fixed bed infra.ed hea.ing rea.tor(co-current)presented the ma.sive seconda.y rea.tions,which lowered the sha.e oil production(Sira.a.d et a..,2017).Conversely,the cross-current infra.ed a.hieved sha.e oil yields higher tha. the Fischer a.sa. oil yield(13.07 wt%of dry ba.is),such a. 117.7%of the Fischer a.sa. yield a. our rea.ized highest hea.ing ra.e of 7℃/s under a.specified pyrolysis tempera.ure of 550℃.The sha.e oil from the cross-current infra.ed hea.ing rea.tor wa. obviously hea.ier tha. the oil obta.ned from the cocurrent hea.ing ***,the infra.ed cross hea.ing evidently suppressed the seconda.y rea.tions towa.d *** rea.ized sha.e oil yield could rea.h 13.67 wt%or 122.5%of the Fischer a.sa. yield under reducing pyrolysis pressure of 0.6 a.m,indica.ing tha. lower pressure is a.so beneficia. to the relea.e of vola.ile a.d reduction of the seconda.y cra.king *** work shows essentia.ly tha. the infra.ed cross hea.ing provides a. effective merge of the a.va.ta.es from quick hea.ing a.d minimiza.ion of seconda.y cra.king rea.tions to ena.le the sha.e oil yields being higher tha. the Fischer a.sa. oil yield.
