[Gasification] eliminating carbon monoxide from coal gas

[linvent at aol.com]

 My question is why does one want to get rid of CO in the fuel gas as it has a higher heating value than that of hydrogen and without CO, an engine derating is much more significant just using hydrogen. The one component that significantly increases engine performance is methane in the produced gas as small quantities make a significant improvement in engine rating on produced gas.?

  If the gasifier is air blown with some steam added the reaction will remain exothermic. If the gasifier is brought up to temp with air and then switched to steam blown then the reaction will be endothermic on pure steam and will need to be toggled back to air blown hence town gas.

Is this reaction sustainable or will the charcoal fire get extinguished due to prolonged passage of steam?


The answer to this question should determine the continuation of the discussion.

Hello Anand
Some of? the CO can be removed using the water gas reaction. This well known stoichiometry of the water the water-gas shift reaction is : co+h20 <=>h2+co2+heat ( exothermic)
In an efficient heat integrated scheme , the heat of the reaction can be recovered as superheated high pressure steam.

Coal gas as automotive fuel
Agriculture, forests and urban centres ?in India produce annually
about 1000 million tons of combustible waste biomass. Its energy
content is almost 3 times as much as the petroleum that we currently
use in our country.? Samuchit Enviro Tech developed a simple and
nonpolluting technology for converting combustible biomass into
charcoal. When hot charcoal is treated with steam, it produces coal
gas, consisting of a mixture of carbon monoxide and hydrogen. We have
used this reaction in an experimental stove, in which the coal gas is
used as fuel. ??Can anybody suggest a simple method of removing carbon
monoxide from coal gas?
