Fig. 2 shows the TG/DTG curves of Jingou lignite, wheat straw
and plastic waste and their mixtures. From Fig. 2(a) it can be
observed that at 200 ◦C the wheat straw begins to decompose
and at 317 ◦C the weight loss rate is the highest, and about 70%
of wheat straw loses when the temperature is 500 ◦C. The plastic waste (PET) begins to decompose at 400 ◦C, and the maximum
weight loss rate appears at 435 ◦C; and about 84% of the weight
looses when the temperature increases to 500 ◦C. The weight of
lignite first decreases at 100 ◦C, and then about 45% of the weight
looses when the temperature increases from 350 ◦C to 800 ◦C, and
at 495 ◦C the weight loss rate is the highest. From Fig. 2(a) one
