摘要：

In this paper，the pressurized gasification of nitrogen-rich wood waste was carried out on a pressurized thermogravimetric，and the effects of reaction pressure were studied on gasification products and processes. The experimental results showed that the high pressure on the pressurized thermogravimetric inhibited the precipitation of volatiles，but increased the reaction rate in the gasification stage above 700 ℃，and reduced the end temperature of gasification from 1104 ℃ at atmospheric pressure to 1076 ℃ at 1 MPa pressure. In the pressurized entrained-flow bed，the increasing of gasification pressure could significantly improve the quality of syngas，and the concentrations of CO，H2 increased individually. Besides，the carbon conversion，gas yield and low calorific value all increased obviously. With the increase of gasification pressure，the concentrations of HCN and NH3 of the gaseous products gasification from nitrogen-rich wood waste decreased rapidly from 4606 and 2405 mg/m3 to 393 and 622 mg/m3 respectively. © 2023 Science Press.
