Development of high performance catalysts is a key to produce cleaner fuels by using conventional refinary plants. Unsupported Co (Ni)-Mo-S fine particles were prepared and their HDS activities of gas oil were examined by using a micro-autoclave and a continuous microreactor. The unsupported catalysts had lower performance baced on the Mo amount, but higher performance based on the catalyst amount than commercial supported catalysts. The unsupported CoMoS could reduce the sulfur content of gas oil below 15ppm at 340℃, LHSV 1.5, but the deactivation occurred significantly. The retarding effect of nitrogen compounds on HDS was much larger for the unsupported catalysts than for the supported catalyst.
