Hydrogasification of low-oxygen semi-coke to produce methane by consuming less hydrogen
The presented work aimed at investigating the hydrogasification of low-oxygen semi-coke.For comparison, the hydrogasification of lignite was conducted.Variation of gaseous products concentration and reaction rate of the semi-coke hydrogasification process were investigated.The results shown that the methane yield of low-oxygen semi-coke is 24.8% greater than the lignite, but also the hydrogen consumption reduced greatly; the hydrogasification process can be divided into three stages: hydro-pyrolysis stage, rapid hydrogasification stage and slow speed hydrogasification stage; the difference of the reactive is attributed to different carbon structure forms.
