过氧化氢对光催化氧化解聚大港减压渣油的影响
Effect of hydrogen peroxide on Dagang vacuum residue oxidation depolymerization assisted with photo-catalytic
摘要
Abstract
The Dagang vacuum residue ( DVR) was oxidized by hydrogen peroxide assisted with photo-catalytic. And the oxida-tion efficiency was analyzed through gas chromatography-mass spectrometry ( GC-MS) and Fourier transform infrared spectrosco-py ( FTIR ) . The results indicate that hydrogen peroxide plays an important role of promoting the photo-catalytic oxidation process. And about 70% of the alkane in DVR is gradually converted into some strong polar and easily separated oxygenated compounds, and its relative content reaches 92. 94% in DVR. The compounds mainly include 36. 05% organic carboxylic acids, 14. 56% organic esters, and 9. 05% other chain oxygenated compounds ( ether, ketone, and phenol products etc. ) . The heterocyclic compounds reaches 21. 57%, of which five-membered cyclic ether compounds ( furan) accounts for 19. 12%. And the long chain hydrocarbons can be depolymerized through reduced carbon chain unit number. And the amounts of hydrogen peroxide, catalyst and heavy oil, as well as the different solvents have all influences on hydrogen peroxide oxidation.关键词
