Fuel Chemistry Coal science (40 hours of Course) Petroleum (4 hours of Course) Natural gas (4 hours of Course) Introduction Energy is the important material base and production factors for supporting social development economical growth .At the same time , energy not only provides the guarantee for agriculture , offers the motive forces for industry , but also propels technical progress and the society forward . According to the ways of exploitation and utilization ,energy is classified into two kinds ,namely , primary energy secondary energy . Primary energy means those which exists in the natural world in extant form ,including fossil energy(coal, petroleum, natural gas ) , nuclear fuel , renewable energy(solar energy , wind energy, geothermal energy, tidal energy) . Secondary energy means those which are processed and transformed from primary energy for the sake of improving the energy utilization efficiency or protecting the environment ,such as electric power ,town gas ,coke ,diesel oil ,gasoline ,kerosene .

In the world , fossil energy is rich ,but to every country , the regional distribution of primary energy is extremely uneven . Top 10 countries reserves centralize about 90.8% coal ,84% petroleum 76% natural gas in the world total . 1) Coal mainly dis
