Coal-mining region deposits include both lignite (brown coal) and black coal. The premier producing areas for Australian coal are the Bowen Basin in the state of Queensland, the Hunter Region in the state of New South Wales, and the Latrobe Valley in the state of Victoria. China is currently the world's largest coal miner, and it is also the largest consumer of coal in the world. China’s coal output has continued to increase and its production capacity has expanded at an unprecedented rate, with an annual increase in production of 200 million tonnes on average. In 2012, the total output of coal
Coal gasification refiner wants to produce alkanes (i.e., hydrocarbons present in natural gas, gasoline, and diesel fuel), the coal gas is collected at this state and routed to a Fischer-Tropsch reactor. If, however, hydrogen is the desired end-product, the coal gas (primarily the CO product) undergoes the water gas shift reaction where more hydrogen is produced by additional reaction with water vapor: Although other technologies for coal gasification currently exist, all employ, in general, the same chemical processes. For low-grade coals (i.e., "brown coals") which contain significant amounts of water, there are technologies in which no steam is required during the reaction,
