摘要

摘要: 采用快速热解固定床在恒温热解条件下研究了不同混合比例不同煤阶煤与重油残渣共热解焦的形貌和焦产率的规律，进而在热重分析仪上采用非等温气化方法研究了煤焦、重油残渣焦及混合焦的气化反应性。结果表明，煤与重油残渣共热解焦有明显的结块现象，但焦产率与理论值一致，表明共热解过程中两者没有相互作用。重油残渣焦的气化反应性较褐煤和烟煤的低，比无烟煤活性略高，重油残渣与褐煤和烟煤混合焦气化反应速率比计算值高，表明气化过程有促进作用存在，进一步分析表明，煤中的矿物质如Ca、Fe，对重油残渣气化有一定的催化作用。

Abstract: In order to find an efficient and feasible technological route to dispose and utilize deoiled asphalt (DOA, a byproduct of solvent deasphalting process), the co-pyrolysis/gasification of DOA with different rank of coal was investigated. A series of isothermal co-pyrolysis experiments were conducted in a fixed bed reactor to observe the characteristics of the char yields and the pattern of the blends. Then a set of non-isothermal experiments were performed by thermogravimetric system to evaluate the gasification characteristics of the chars of coal, DOA and the blends. It is observed that the co-pyrolysis char formed as blocks, while the char yields show that the co-pyrolysis process has no interaction between the two resources. The gasification reactivity of the DOA char is lower than that of lignite and bituminous coal char, and is a bit higher than that of anthracite char. The gasification reactivity of the blended char of DOA with lignite/bituminous coal is found higher than that of the calculated, which clearly demonstrating that the synergetic effect existed during the gasification process, and that is mainly caused by the minerals such as Ca, Fe contained in coal char.
