| 摘 要： | 在溶煤比为2.75∶1,氢初压为6.0MPa和反应时间为60min条件下,考察了温度、飞灰加入量、CoSO4和NiSO4用量及其加入方式等因素对五彩湾煤直接液化性能的影响.结果表明,在给定的条件下,在飞灰加入量为3%(daf,质量分数)和温度为415℃时,可获得最大油产率为64.59%;当CoSO4和NiSO4与飞灰和煤样机械混合加入时,对液化油产率和转化率产生负效应;当NiSO4和CoSO4浸渍担载加入时,油产率分别达到68.01%和66.58%.尽管煤质分析结果表明该煤样加氢液化性能较差,但以飞灰、CoSO4和NiSO4为催化剂时,还是获得了良好的液化效果.

| Abstract: | Effects of temperature,contents of steelmaking flue dust,CoSO4 and NiSO4 and adding ways were investigated on liquefaction of coal sample from Wucaiwan under reaction conditions that ratio of solvent to coal was 2.75∶1,reaction time 60 min,and initial hydrogen pressure 6.0 MPa.Results indicated that under the given conditions,we obtained maximum oil yield of 64.59% when the amount of steelmaking flue dust was 3% and temperature was 415 ℃.When CoSO4 and NiSO4 mixed with the dust and sample,yields of oil and conversion decreased.Oil yield were 68.01% and 66.58% respectively,when NiSO4 and CoSO4 were added by supported.We still obtained a good liquefaction results when steelmaking flue dust,NiSO4 and CoSO4 as cata-lysts,although analytical results of the coal sample showed that liquefaction performance of the sample wasn’t enough well. |
