Abstract: In order to discuss the commercialization operation outlook of crop straw gasification technology, this paper analyses technical capability of crop straw gasification for central gas supply, and considers they are different for the components and capability of the central gas supply system, due to the differences of technological way of both the oxygenation gasification technology and the pyrogenation gasification technology, but these two kinds of technology are mature and practical, and both relatively safe and stable. At the same time, there are still a series of problems associated with these technologies that need to be solved or further improved, such as problem of further reducing tar and impurity content of the fuel gas. In succession, it is estimated for commercialization operational capability of the central gas supply system, loss case and profitable case are calculated by using cost-benefit method. The conclusions are that the gas station must be managed commercially and marketability must be enhanced stage by stage with the large-scale development of the gas supply system for the future.
