【Chemical Industry Information】Consumption rate of desulfurization alcohol catalysts
Thread Content
This post was last edited by Xiao Gong 1985 on 2016-3-15 09:13. What is the catalyst consumption rate during the desulfurization of gasoline and liquefied gas? Why is a catalyst added – due to activity degradation or loss? Is the final catalyst in the alkaline slag? Thank you!

The conversion of sodium thiolate is very slow in the absence of a catalyst. It is related to factors such as consumption rate and mercaptan content in the liquefied gas, as well as the amount of alkaline solution and the circulation volume; generally, it should be maintained at 100-200 ppm. Deactivation is caused by aggregation, usually occurring in the alkaline slag, and some also exists in the impurities filtered out by the filters.
