Abstract

Hydrothermal liquefaction of corn stalk under CO atmosphere with three commercial heterogeneous catalysts was performed in a high pressure autoclave. The structure and reducibility of the catalysts were studied by X-ray diffraction and differential thermal gravity under H2 atmosphere. The results indicated that the catalysts greatly increased the conversion of cornstalk yield and heating value of liquid product. The activity order of the catalysts is as follows: JT203 > JT201 > JB-1, which is consistent with the high surface area and low reduction temperature of JT203. The catalysts might favor a hydrothermal liquefaction process through the active H produced by water-gas shift reaction.
