纤维素的加压热解特性及动力学研究
Study on pressurized pyrolysis characteristics and kinetics of cellulose
摘要
Abstract
The cellulose was analysised by pressurized thermo gravimetric analyzer,and TG curves and DTG curves were obtained under different heating rates (5,10,20 K/min) and pressures (0.1,0.5,1,1.5,2 MPa),and pyrolysis kinetic parameters was gained by thermal analysis mathematical methodology.The results indicated that the main pyrolysis region shifted to the higher temperature range and pyrolysis lever increased slightly when raising heating rate no matter what the pressure was;the main pyrolysis region moved to the lower temperature zone,pyrolysis time became shorter and the residue ratio raised when increased pressure and each heating rates;activation energy increased along with the pressure increasing under the same heating rate,and increased obviously at the greater heating rate; pyrolysis activation energy was increased under the same pressure with the heating rate increasing,and increased significantly in higher pressure ;There were existed a good compensation effect between the pyrolysis activation energy and pre-exponential factor under various conditions关键词
