The technology of marsh gas concentrating for VAM was the key technology, which restricted the utilization of low concentration coal-bed gas. Based on the analysis of research on the technology of marsh gas concentrating for VAM of domestic and foreign scholars from different technology, material and method, the staged results and breakthrough were summarized. The separation effect, advantages and disadvantages of cryogenic distillation, membrane separation process, solution absorption process, adsorption stripping process and hydrate synthesis process in different condition were analyzed simultaneously. The utilization prospect of low concentration coal-bed gas was viewed objectively.
