Coliquefaction of coal and biomass waste is an exploration for decrease in the cost of coal liquefaction and promotion of effective utilization of biomass waste Tests of coliquefaction of Xinwen coal and sawdust are carried out in an autoclave manufactured by Autoclave Engineering Inc USA The effects of reaction parameters, i e , temperature, time, cool hydrogen pressure, atmosphere and solvent, on the coliquefaction process are investigated Results show that the addition of sawdust to coal can not only make the reaction conditions milder but also enhance the conversion of coal and at the same time improve the quality of the liquid products The liquid products from the coliquefaction contains more oil than those from coal liquefaction alone Sawdust, in some sense, can donate hydrogen in coliquefaction When tetralin used as solvent under initial hydrogen pressure of 3 40MPa and reaction time of 30 min at 400℃, conversion of coliquefaction can reaction 82 4% with oil yield 37 8%

The coliquefaction of Xianfeng coal with low density polyethylene (LDPE) using 3H labeled solvent has been conducted The effects of FAMo and Fe 2O 3+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

The coliquefaction of Xianfeng lignite with low-density polyethylene (LDPE) using radioisotope 3H labeled polyethylene has been conducted. The effects of FAMo catalyst and different 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 free radical groups containing hydrogen of hydrogen-rich plastic LDPE do play a role of hydrogen donor in coliquefaction of Xianfeng coal with LDPE, and the free radical groups containing hydrogen of LDPE transfer to the primary coal liquefaction products without going through the transmittance of hydrogen-donatable solvents. The FAMo catalyst can improve the donating hydrogen of LDPE plastics to coal liquids. When hydrogen non-donor solvent was used in coliquefaction in the presence of FAMo catalyst, the hydrogen transfers very quickly from the free radical groups containing hydrogen of LDPE to coal, and the competitive transfer of hydrogen occurs at the initial reaction stage of coal coliquefaction with LDPE.

采用放射性同位素3H标记的聚乙烯塑料进行了先锋褐煤与低密度聚乙烯 (LDPE)的共液化示踪试验 ,并考察了钼灰 (FAMo)催化剂和不同溶剂的影响。示踪试验结果表明 ,在先锋煤与LDPE共液化过程中 ,富氢塑料LDPE中的含氢基团确实起着供氢作用 ,而且这种含氢基团向煤液化自由基的氢转移无需经过供氢溶剂进行传递。钼灰催化剂能够加速LDPE塑料的供氢作用。使用非供氢溶剂时 ,在煤与LDPE共液化反应初期 ,LDPE中的含氢基团在钼灰催化剂作用下较易向煤热裂解产物转移 ,并出现供氢竞争现象。
