Abstract

This study investigated the microwave-assisted catalytic fast pyrolysis (MACFP) of straw stalk and soapstock with HZSM-5 as a catalyst. The effects of pyrolysis temperature, catalyst:feed ratio, and straw stalk:soapstock ratio on bio-oil yield and composition were discussed. Results showed that temperature greatly influenced the yield and product distribution of bio-oil. The maximum bio-oil yield and highest proportion of aromatic hydrocarbons were obtained at 550 °C. Adding HZSM-5 decreased bio-oil yield but improved bio-oil quality. Co-feeding straw stalk and soapstock can improved the proportion of aromatic and aliphatic compounds. The optimal range of straw stalk:soapstock ratio was 1:1 to 1:2. Moreover, biochar is rich in various essential elements and can be used as good soil amendment.
