The amount of carbon monoxide and hydrogen slowly increases, then being gradually decreased completely with reaction, until produced without gas, most
Tube furnace is cooled to room temperature afterwards.
The solid product obtained after being cooled down to the present embodiment carries out XRD detections, as shown in figure 3, solid is produced as we know from the figure
Contain CaS and a small amount of silica in thing, while using the S in iodometric determination residue2-Content, calculates according to stechiometry
The CaSO gone out in residue4With the amount of CaS, it is calculated analytically and obtains, does not have CaSO in residue4, the above analysis can draw phosphorus stone
CaSO in cream4It is completely converted into CaS.
The resolution ratio of lignite is calculated according to following equation：
Because except CaSO in raw material ardealite4Other compositions content it is relatively low, raw material ardealite impurity is defaulted as herein is
0, analysis is computed, lignite resolution ratio is 90.29%, and the H:Cmoleratio of the present embodiment gained gas is 1.5, meets synthesis gas
The requirement of the coarse raw materials gas H:Cmoleratio 1.0-5.0 ratios of downstream product.

The amount of carbon monoxide and hydrogen slowly increases, then being gradually decreased completely with reaction, until produced without gas, most
Tube furnace is cooled to room temperature afterwards.
The solid product obtained after being cooled down to the present embodiment carries out XRD detections, as shown in figure 4, solid is produced as we know from the figure
Contain CaS and a small amount of silica in thing, while using the S in iodometric determination residue2-Content, calculates according to stechiometry
The CaSO gone out in residue4With the amount of CaS, it is calculated analytically and obtains, does not have CaSO in residue4, the above analysis can draw phosphorus stone
CaSO in cream4It is completely converted into CaS.
The resolution ratio of lignite is calculated according to following equation：
Because except CaSO in raw material ardealite4Other compositions content it is relatively low, raw material ardealite impurity is defaulted as herein is
0, analysis is computed, lignite resolution ratio is 93.26%, and the H:Cmoleratio of the present embodiment gained gas is 1.61, meets synthesis gas
The requirement of the coarse raw materials gas H:Cmoleratio 1.0-5.0 ratios of downstream product.
