Abstract: Biomethane has developed rapidly in western countries，such as Germany and Sweden，but it is still in its infancy in China though biomethane is an important renewable energy made from organic sources. At present，the bottleneck limiting its large-scale application is unclear mechanisms of high efficiency conversion and effective energy utilization in biomethane process. In this work，the key problems in biomethane process were discussed based on new theory of chemical engineering. It was concluded that that rapid progress can be made in biomethane industry in China with the help of new theory of interface transport，new micro and nano materials and system optimization methods.

Key words: biomethane, transform efficiently, chemical engineering, interface, system optimization
