AI Technical Summary

Problems solved by technology

This series of catalysts has strong impurity resistance and good economy. The slight disadvantage is that the start-up temperature is relatively high.
[0016] The current commercialized nickel-based powder catalysts with 55% and 65% nickel content use high-pressure reactors to carry out hydrogenation and decolorization reactions on C5 / C9 copolymerized petroleum resins, and hydrogenation reactions are carried out at relatively high temperatures and pressures. The hydrogenation rate is still not high
