摘要

摘要: 用共振搅拌反应器研究了煤液化过程中溶剂的作用,结果表明,用大分子直链脂肪烃、单环苯系列化合物作溶剂,煤转化率较低。比较不同环数化合物作溶剂对应的煤转化率可得,单环苯系列< 两环萘系列<三环蒽、菲。使用芘溶剂和萘溶剂转化率相近;酚类化合物不适合作煤液化的溶剂;同系列物相比,煤转化率次序为,部分氢化芳香化合物作溶剂>带侧链的芳香化合物作溶剂>芳香化合物作溶剂>完全氢化芳香化合物(环烷烃)作溶剂。气氛对煤转化率的影响与所用溶剂的种类有关,用十氢萘和甲基萘做溶剂时,气氛的影响很小,使用四氢萘时,气氛的影响很大。

Abstract: Using a resonance agitation reactor the effect of solvent on liquefaction of Chinese Yangcun bituminous coal under H₂ or N₂ under 7.0 MPa (cold) was studied. The results show that chain hydrocarbon and mono-ring series compounds are not good solvents. For the same series solvents, partly hydrogen aromatic compounds are the best solvents, followed by aromatic compounds with chain and aromatic compounds. Cycloparaffin and phenols are bad solvent. Decalin and methylnaphthalene do not change H₂ into active hydrogen because coal conversion is similar under H₂ or N₂. Tetralin can change H₂ into active hydrogen.
