在小型高压反应釜中以四氢萘为溶剂，氢气和合成气为液化反应气，通过对不同液化条件下所得液化产物的收率及性质分析，考察了不同液化条件(反应温度、反应时间、反应气压力)对锯屑高压液化行为的影响；同时在相同液化条件下，通过液化产物收率和性质的分析，考察了气氛对锯屑高压液化行为的影响，探讨了用合成气代替氢气进行液化的可行性。

In order to meet the need of economic development for large-specification roll of steel plates, technical improvements have been carried out in the hot-rolling mill. The six sets of high pressure water pump, which cannot provide high enough speed of water supply for rolling, is replaced using three sets of high pressure centrifugal pump. The working mode of three sets of high pressure centrifugal pumps is that two pumps work and another one is spare. After the project has been carried out other problems emerge, for example, the electromotor becoming very heat and the pump being frequently attainted.
