Removalof solphur with molybdenum catalyst
WebAfter drying, the catalysts were subjected to second calcination to decompose the precursor to SnO 2 and to produce the targeted catalyst. Apparently, the reported traditional strategies for Sn/SBA-15 are rather complicated, and SBA-15 after removal of the template was used as a support, and less attention has been paid to template occluded SBA-15. WebFig. 7a exhibits the catalytic performances of immobilized catalysts with molybdenum oxide in oxidative sulfur removal. Results show 98.6 % sulfur removal in the W-G catalyst after 120 min.
