Microwave‐assisted catalytic pyrolysis of theEupatorium adenophorumfor obtaining valuable products

Abstract

AbstractEupatorium adenophorum, global exotic weed, is used as feedstock in the presence of two catalysts to produce renewable biofuels and green chemicals combining with the advantage of microwave heating and catalytic pyrolysis. The effect of catalyst on yield of pyrolysis products is studied. And the pyrolysis product produced from with and without catalytic pyrolysis is analyzed for performance comparisons. The results show that catalytic pyrolysis tends to produce more bio‐oil and less bio‐gas. The bio‐oil from catalytic pyrolysis has more alkane and ketone, and less carboxylic acid compound compared to non‐catalytic pyrolysis, indicates that catalytic pyrolysis could upgrade the quality of bio‐oil. Compared to bio‐gas of non‐catalytic pyrolysis, the catalytic pyrolysis has larger CO and less CO2content, particularly for Sodium chloride (NaCl) catalyst pyrolysis. The bio‐char of NaCl catalytic pyrolysis has higher Brunauer–Emmett–Teller (BET) surface area and total pore volume. The above analysis indicates that catalysts pyrolysis makes the properties of pyrolysis product tend to good tendency.
