Honggen Peng, H. Zhao

Open publisher page 1 citations

Abstract

The mesoporous molecular sieve catalyst Co/SBA-15 was synthesized by two steps synthesis method, based on which oxidized wax was prepared. The emulsification of oxidized wax was carried out by employing Span-80, Tween-80, and stearic acid as compound emulsifier. The results showed that when the mass ratio of Span-80, Tween-80, and stearic acid was 5.5:3.6:0.9, emulsifying temperature was 75°C, emulsifying time was 55 min, emulsifier amount was 7.3%, and water consumption was 69.96%. The emulsion performance of oxidized wax was improved greatly compared with ordinary paraffins.
