摘　　要：以核桃壳和褐煤为研究对象,系统考察了核桃壳/煤质量配比、原料/四氢萘溶剂质量比、反应温度、反应时间及催化剂对共液化效果的影响。结果表明,当核桃壳/煤质量配比为50/50,原料/四氢萘溶剂比例为1/10,反应温度300℃和反应时间为31min时,可获得较好的共液化效果。碳酸钠与硫铁催化剂对核桃壳与煤的共液化均具有明显的催化作用,转化率和油产率可获大幅提高。核桃壳与煤的共液化存在明显协同作用,且这种作用在催化剂条件下更明显。The co-liquefaction of walnut shell and coal in 1,2,3,4-tetrahydmnaphthalene was investigated. The influences of walnut shell/coal mass ratio, mixture of walnut shell and coal/solvent mass ratio, reaction temperature, reaction time and the catalyst on the conversion and yield of products were studied. The results showed that when the optimum liquefaction conditions were carried out with walnut shell/coal mass ratio of 50/50, the mixture/solvent mass ratio of 1/10, reaction temperature of 300℃, reaction time of 30min and without catalyst, the conversion and yield of oil were 73.92% and 46.22%, respectively. Both catalysts of sodium carbonate and ferric sulfide （FeSx） had an obvious effect on the co- liquefaction of walnut shell and coal. And these catalysts could improve the conversion and oil yield effectively. There was an obvious synergy in the co-liquefaction, and the synergy became more markedly by using sodium carbonate and ferric sulfide as the catalyst.
