Abstract

Abstract

Pyrolysis and gasification technology, as a harmless treatment method of MSW, has great research significance. The MSW fixed-bed pyrolysis and gasification model was established using Aspen Plus software. The effects of gasification temperature, gasification pressure and air equivalent ratio on the pyrolysis and gasification process of MSW were discussed based on model verification. The quadratic regression orthogonal test method was used to obtain the mathematical relationship between gas yield, gas calorific value, gasification efficiency and process parameters. Matlab software was applied to solve the equation and get the best combination of process parameters. The results showed that with the increase of gasification temperature, the calorific value of gas production increased slightly, and the produced gas yield and gasification efficiency both increased first and then tended to be stable. The air equivalent ratio had the most significant influence on the gasification efficiency, followed by the gasification temperature, and then influence of gasification pressure. When the gasification temperature was 891 ℃, the gasification pressure was 1.01×10⁵ Pa, and the air equivalent ratio was 0.2, the gasification efficiency reached a maximum.
