摘要
Abstract
The coliquefaction of Xianfeng coal with low-density polyethylene (LDPE) using 3H labeled solvent has been conducted. The effects of FAMo and Fe2O3+S catalysts, and solvents were examined. The 3H concentration in the reaction products was determined by a liquid scintillation counter to study the hydrogen transfer pathway. The results show that in the primary reaction of coal coliquefaction with LDPE, the coal was thermally decomposed and hydrogenated by hydrogen atoms mainly released from the solvent, tetralin (THN), and this hydrogen supplied from tetralin was not influenced by the catalyst. When the mixture of hydrogenated anthracene oil (HAO) and tetralin was used as the coliquefaction solvent in the presence of FAMo catalyst, the competitive transfer of hydrogen from strong donating hydrogen solvent, HAO, to the primary coliquefaction products occurs at the initial liquefaction reaction stage.关键词
