Abstract

Catalytic fast pyrolysis is one of the most promising and prevailing technologies for the improvement of bio-oil quality. In this contribution, catalytic fast co-pyrolysis of mushroom waste and waste oil over HZSM-5 zeolite catalyst was conducted to promote the production of aromatics using pyrolysis–gas chromatography/mass spectrometry. The effects of pyrolysis temperature and waste oil to mushroom waste mass ratio on the pyrolytic product distribution were investigated and analyzed. The results showed that with temperature increasing, the relative contents of hydrocarbons increased at first and then decreased, and 600 °C was an optimum temperature as the maximum yield of hydrocarbons could be reached. Besides, the waste oil to mushroom waste mass ratio was of great significance in the catalytic fast co-pyrolysis process, and the total relative contents of hydrocarbons increased with the increasing of waste oil to mushroom waste ratio. On the other hand, a significant synergistic effect between waste oil and mushroom waste was studied during catalytic fast co-pyrolysis, which played an effective role in promoting the production of aromatics remarkably. Catalytic fast co-pyrolysis of waste oil and mushroom waste made a significant contribution to the practical utilization of biomass pyrolysis and provided an effective and efficient way to promote the upgrading of bio-oil.
