《IGCC粗煤气高温脱硫（英文版）》系“能源与环境出版工程”(第二期)之一，较为全面地介绍了整体煤气化联合循环发电(1GCC)的高温脱硫技术。书中系统介绍了单一金属氧化物脱硫剂、复合金属氧化物脱硫剂、稀土氧化物脱硫剂和纳米金属单质脱硫剂的制备方法；对不同气氛下各脱硫剂的反应机理、脱硫反应动力学、再生后脱硫剂的脱硫活性和使用循环次数进行了相应的实验研究；此外，该书提供了碳气凝胶(作为脱硫剂的载体)具体的制备方法和改性措施，介绍了其在吸附、催化等领域的应用前景。通过阅读该书，读者可以全面了解lGCC洁净发电技术中的关键环节和未来有可能实现的新型技术应用。

热粗煤气是不脱焦油的煤气，由于煤气中含有焦油，极易堵塞管道，在工业界很少应用。煤气是以煤为原料加工制得的含有可燃组分的气体。根据加工方法、煤气性质和用途分为:煤气化得到的是水煤气、半水煤气、空气煤气(或称发生炉煤气)，这些煤气的发热值较低，故又统称为低热值煤气;煤干馏法中焦化得到的气体称为焦炉煤气，高炉煤气。

煤气是由含碳物质不完全燃烧时发生的气体，主要成分是一氧化碳，无色无臭，有毒，被人和动物吸入后与血液中的血红蛋白结合(比氧与血红蛋白的结合能力强，造成一定程度的缺氧)能引起中毒。也叫煤毒。发生炉煤气分为单段发生炉煤气和双段发生炉煤气，两种煤气的成分含量有所不同2100433B

进入低温甲醇洗粗的煤气中CO含量过高，易造成CO分压高，吸收塔压差升高，影响甲醇对CO₂的吸收效果;粗煤气中的NH₃含量高，进入甲醇洗系统后，易造成煤气低温冷却器碳酸氢铵结晶堵塞，影响生产正常运行;粗煤气中煤粉等杂质进入甲醇洗系统，易造成固体物质在溶液换热器列管内聚集，影响换热器的换热效果或在吸收塔塔盘上聚集，使塔压差升高，影响吸收效果。

为保证吸收塔的正常运行，可采取以下防范措施，防止过多的杂质进入系统:

(1)变换系统尽量控制出口气体中CO含量在工艺指标范围内，一般情况下不宜采取提高CO含量来增加液氮洗冷量;

(2)变换系统严格控制好煤气洗涤效果，洗涤后的煤气温度不超过40℃ ，以防气体中的氨洗涤不干净，将氨带入甲醇洗系统;

(3)绝对禁止开变换炉副线来调整粗煤气中CO含量，特殊情况下要适当提高CO含量，也只能通过变换工段调整工艺来实现，以防将固体杂质带到甲醇洗系统。
