Brown coal mining limits in North Bohemia in the case of Bílina had been under preparation for a long time with the cooperation and agreement of the surrounding communities. It would ensure work for a further generation of people from 2030 to 2055 and would guarantee heating for four million people dependent on lignite-fired central heating systems, he said. According to Environment Minister Brabec, it would have to be clear before any possible lifting of the limits that there was a need for the coal. "We have to be sure that we really need the coal, when we will need it and what we need it for.
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,
