摘要/Abstract

摘要： 煤的催化气化在国内外已被广泛研究, Ca作为一种对煤气化反应具有催化作用的碱土金属催化剂也受到许多研究者的关注。本文总结了可作为煤气化反应催化剂的Ca的类型, 论述了Ca催化煤气化反应的机理, 分析了影响Ca催化作用的主要因素, 指出当Ca与其他物质共同作为煤气化反应的催化剂时, 往往可以产生协同效应, 更有效地催化煤气化反应的进行。同时提出了今后在Ca催化煤气化反应方面所应进行的研究内容, 认为进一步探讨Ca在煤气化反应过程中发生的催化机理, 开发使用廉价的石灰石、熟石灰, 并且与其他物质, 尤其是纸浆黑液共同作为煤气化反应的催化剂很有必要。

Abstract: Catalytic gasification of coal has been widely investigated. As a catalyst for coal gasification, calcium has been concerned by many researchers. In this paper, the types of calcium that can play catalyst role in coal gasification are summarized. The mechanism and influencing factors of calcium catalytic coal gasification are discussed. It is pointed out that calcium can accelerate the coal gasification rate more effectively because of the synergistic effect when it is selected to catalyze coal gasification together with other materials. Meanwhile, the research on calcium catalytic coal gasification in the near future is prospected. It is suggested that the mechanism of calcium catalytic coal gasification should be further discussed. It is necessary to develop the catalytic coal gasification technology using limestone or slaked lime mixed with other materials, such as black-liquor.

Key words: coal gasification, catalysis, calcium catalyst, limestone
