本发明技术方案如下：
一种复合型油溶性催化剂在油煤共炼工艺中的使用方法，其特征在于原料为渣油和煤粉，原料油与油溶性催化剂先在原料/催化剂混合系统进行混合，再加入煤粉，经充分溶胀，使催化剂在反应物料中的浓度达到均一状态；混合完成的反应物料与催化剂和氢气进入反应器，进入方式为下进上出；所述油溶性催化剂为：所述油溶性催化剂活性组分为V、Ni组合。优选的催化剂与原料油混合温度为100-150℃，混合时间为30-50分钟。
优选的催化剂以活性金属计添加量不超过反应原料量的1wt％。
优选的反应器为空筒结构的悬浮床反应器，反应器串联数量为1-2台。
优选的反应温度不超过450℃，反应压力不超过20MPa。
本发明的技术效果如下：
本发明使油溶性催化剂先与原料油互溶混合、再加入煤粉制备油煤浆、溶胀、加入氢气、进入床反应、分离，并限定了具体的操作条件，催化剂在原料中得到均匀分布，进而发挥良好的催化效果。所述油溶性催化剂活性中心为V、Ni组合，本发明可用于油煤共炼，具有如下述突出优势：
