| Abstract: | To realize the domestic application of hydrophobic silica gel for vapor recovery and solve the potential safety problem of the active carbon, the experimental preparation of hydrophobic silica gel was carried out. The optimum conditions obtained by orthogonal experiments were as following: the original is Atype silica gel, the reagent is DCDMS, the qualitative rate between reagent and original is 1:20, reactive temperature is 30℃ , and the reactive time is 2h. The static adsorption of oil vapor is 300.5g/kg of the product obtained under the conditions, and the hydrophobic index is 72.3%. |
