气化反应

气化反应(Gasification)是转换有机的或化石燃料的碳质物料为一氧化碳,氢气和二氧化碳的方法。这是通过在高温下(>700℃)时,物料不燃烧,并与受控量氧气和/或水蒸气发生的反应来实现的。所产生的气体混合物称为合成气(syngas),本身是燃料。如果从生物质得到的气化化合物,气化反应本身与产生气体的燃烧所产生的动力被认为是可再生能源的来源。

气化反应的优点在于,使用合成气可能比原燃料的直接燃烧更有效,因为它可以在较高的温度被燃烧,甚至在燃料电池中被燃烧,以使由卡诺定理定义效率的热力学上限更高或(在燃料电池中的情况下)不适用。合成气可能直接在燃气内燃机中被燃烧,被用于产生甲醇和氢,或通过费托合成方法被转化为合成燃料。气化也可以开始使用本来会将被丢弃的材料,例如生物降解垃圾。另外,高温工艺精炼出腐蚀性的灰渣元素如氯化物和钾,允许从来自存在问题燃料生产出清洁合成气产品。化石燃料的气化目前被广泛使用以工业规模生产电力。

Gasification 气化反应

Adler Diplomat 3 with gas generator (1941)
Main gasifier types
HTCW reactor, one of several proposed waste gasification processes. According to the sales and sales management consultants KBI Group a pilot plant in Arnstadt implementing this process has completed initial tests.[13]

Gasification is a process that converts organic or fossil fuel based carbonaceous materials into carbon monoxide, hydrogen and carbon dioxide. This is achieved by reacting the material at high temperatures (>700 °C), without combustion, with a controlled amount of oxygen and/or steam. The resulting gas mixture is called syngas (from synthesis gas or synthetic gas) or producer gas and is itself a fuel. The power derived from gasification and combustion of the resultant gas is considered to be a source of renewable energy if the gasified compounds were obtained from biomass.
