Abstract


With China's rapid economic development, rapid growth in demand for energy. Therefore, for increasingly scarce oil resources, the status quo of China's energy and resources must be combined with the actual situation of a diversified energy strategy. Methanol fuel as alternative energy sources, has fully demonstrated its clean, environmentally friendly advantages. Development of coal-based methanol fuel, not only can save oil resources, but also to promote the development of coal chemical industry, has a good economic and environmental benefits. China's methanol gasoline research and extension work has already yielded results. But there is most people do not know enough of methanol gasoline, for its power, economy doubts. When methanol as a vehicle fuel, high calorific value rose to methanol when the main parameters for the experimental determination of calorific value of methanol with the establishment of alcohol fuel heating value estimate theoretical relationship has important significance. At present, China coupled with different proportions of methanol gasoline octane no clear method of calculating this paper, these two aspects were studied in detail. Mainly in the following aspects. Thesis of three gasoline components include straight-run gasoline oil, catalytic cracking and catalytic reforming of gasoline octane number of gasoline and heating value were studied, and the three components of oil physicochemical characteristics were analyzed, and use linear regression method for linear association with its octane identify methanol gasoline octane rating method. According to the experimental results, although the straight-run gasoline octane number lower, but higher calorific value; highest catalytic reforming of gasoline octane, low calorific value; FCC gasoline in between. Therefore, in our gasoline components, increasing the proportion of catalytic reforming of gasoline can not only improve the octane number, but also can improve the quality of the oil. Straight-run gasoline can be used as a component of methanol gasoline oil used to achieve straight-run gasoline and methanol in octane number, calorific value, low temperature start sexual complementarity. In this paper, the calorific value of methanol gasoline were measured and re-fitting the fuel calorific value is calculated. Through analysis and comparison prove a formula can be used as re-fitting the fuel calorific value calculation formula. Finally thesis methanol gasoline power, economy and emission characteristics were bench experiments, the sexual gratification of methanol gasoline powered vehicle fuel requirements, economy is higher; emissions than conventional gasoline, emissions by taking unconventional Measures can be controlled and reduced.
