<p>A process for the manufacture of town gas from landfill gas comprises the steps of;(a) recovering a landfill gas from a landfill site, (b) removing contaminants and water from the landfill gas and adjusting the carbon dioxide level in the resulting landfill gas to give a purified mixed gas stream comprising carbon dioxide and methane,(c) forming a hydrogen-containing gas stream by reforming a first portion of the mixed gas stream, and(d) mixing a second portion of the mixed gas stream with the hydrogen-containing gas. Volatile organic contaminants may be removed by a cryogenic capture step. An apparatus for carrying out the process is also described.</p> |
