英文摘要A novel two-step catalytic co-pyrolysis (TSCCP) process is proposed through coupling advantages of conventional two-step catalytic pyrolysis (TSCP) and one-step catalytic co-pyrolysis (OSCCP) for producing aromaticrich oil using walnut shell (WNS) and LDPE as feedstock. Co-pyrolysis of three WNS components (hemicellulose, cellulose and lignin) with LDPE are performed to validate the necessity and rationality of TSCCP. And effects of first step pyrolysis temperature (T1) and residence time (Rt1) on product distributions of TSCCP are investigated. When T1 and Rt1 are 550 degrees C and 7.5 s respectively, the oil yield is increased by 59.1% and 15.7% respectively compared with that of conventional TSCP and OSCCP. The selectivity toward aromatics is as high as 82.5%, and the selectivity of oxygenates is reduced to less than 1%. The excellent results of TSCCP are attributed to preventing secondary reactions led by higher temperature for hemicellulose and cellulose components, the enhanced conversion due to activation effect from lignin component, and the synergetic effect between WNS-derived oxygenates and LDPE-derived hydrocarbons.
