The effect of pyrolysis temperature on product distribution of CPLPS investigated under heating rate of 10°Cmin-1 and blending ratio of 50(wt)%. Biomass is higher yield to be pyrolyzed than lignite and addition of biomass promotes the pyrolysis of lignite. In the range of the experimental conditions investigated the yield of the product is proportional to pyrolysis temperature. On the other hand, considerable synergetic effects were observed during the co-pyrolysis in a fixed bed reactor leading to increase in oil yield. Maximum pyrolysis oil yield of 27.2% was obtained at pyrolysis temperature of 550°C. The obtained oils are characterized by GC, and elemental analysis.111520211115202149527https://www.naun.org/main/NAUN/geology/2021/a142004-007(2021).pdf10.46300/9105.2021.15.7https://www.naun.org/main/NAUN/geology/2021/a142004-007(2021).pdf10.1016/s1872-5813(11)60044-3W.
