Why must hydrogenation catalyst be pre sulfurized before use

The active hydrogenation catalyst is the sulfide of effective metal components W, Mo, Ni and Co. only in sulfide state can it have high hydrogenation activity, stability and selectivity. The pre sulfurization process of catalyst is the process of restoring its activity, because the sulfurized catalyst is easy to have oxidation reaction with O2

What are the commonly used vulcanizing agents

The function of vulcanizing agent is to provide H2S and metal oxide reaction during vulcanization. Therefore, the selection principle of vulcanizing agent is that it can be decomposed into H2S at a lower temperature during vulcanization, so as to ensure the smooth vulcanization of catalyst and improve the vulcanization effect.

Pre sulfurization mode of catalyst in hydrogenation unit

The wet vulcanization of catalyst can be divided into the wet vulcanization of raw oil containing sulfide and the wet vulcanization with additional vulcanizing agent. Although the self wet vulcanization method of feed oil is simple, the vulcanization effect of catalyst is poor due to the low sulfide contained in feed oil and high decomposition temperature
