Rice straw is one of the major agricultural residues that is generated enormously in Asian countries. Thus, it is critical to develop an efficient process of converting this residue into valuable compounds in replacing fossil-based products. Herein, we developed an economically viable cement catalyst to pyrolyze the rice straw into bio-oil and fuel gas in a batch-type reactor. Under the optimized conditions, the maximum bio-oil yield of 41.07 wt.%, and gas yield of 30.53 wt.%...
