Bioresource TechnologySummary:
Gaining the valuable fuels from sewage sludge is a promising method. In this work, the fast pyrolysis
characteristics of sewage sludge (SS), wheat straw (WS) and their mixtures in different proportions were
carried out in a drop-tube reactor. The combustion reactivity of the residual char obtained was investigated
in a thermogravimetric analyzer (TGA). Results indicate that SS and WS at different pyrolysis temperatures
yielded different characteristic gas compositions and product distributions. The co-pyrolysis of
SS with WS showed that there existed a synergistic effect in terms of higher gas and bio-oil yields and
lower char yield, especially at the WS adding percentage of 80 wt%. The addition of WS to SS increased
the carbon content in the SS char and improved char porous structures, resulting in an improvement
in the combustion reactivity of the SS char. The research results can be used to promote co-utilization
