Brown coal mining limits in North Bohemia Using the coal from the North Bohemian mines in a way that we extract it, burn it, produce electricity from it and export it, and all for very little money because prices today are very low, is absolutely the worst way of using this coal," said Brabec, adding that he did not yet know the details of Mládka proposals. Brown coal mining limits in North Bohemia Territorial limits to the mining of brown coal in North Bohemia are legally binding according to Resolution No. 444 passed in 1991 by the government of the Czech Republic, on the basis of a
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,
