The catalytic performance, production distribut ion and product property were studied under the temperature of 340 ~ 400 and space velocity of 2 ~ 5 h- 1. T he results show that production distribut ion is good, the solidification point of diesel fuel reaches - 29 , and the solidification point of lubricat ing oil reaches - 16 when reaction temperature is 400 , reaction space velocity is 2 h- 1 at normal pressure and without hydrogen. The catalysts are 3 t reated by steam after 4. 5 10 hours, the activity of catalyst is partly react ivated
