Pyrolysis is the first and inevitable reaction steps in the process of the coal and biomass thermal conversion utilization, therefore, it has great significance for the conservation of energy and reduce environment pollution by exploring the stone coal and biomass mixing pyrolysis process with TGA experiments. 2 The Experimental Section (1) Experimental sample processing Stone coal, sawdust and corn stalk three kinds of experimental materials is ground in the mill after natural drying, and sieved to a particle size of less than 0.150mm by using a 100-mesh sieve as the final part of the test sample.
The range of prrolysis temperature is from room temperature to1000℃.The experimental materials dried 2 hours that are placed in the oven before each test. 3 Experimental results and analysis (1) The pyrolysis experimental study of stone coal mixed with biomass Figure 1,Figure 2 is the TG and DTG curves of sawdust,corn stalk are mixed with stone coal respectively pyrolysis according to the ratio of 1:9 under the heating rate of 20 ℃/min.
