The invention relates to a method for producing synthetic hydrocarbons, wherein synthesis gas is produced in that, in a step a), carbon is brought in contact with water or a mixture of carbon and hydrogen is brought in contact with water, namely at a temperature of 800 - 1700 °C. Thereafter, in a step b), the synthesis gas is converted into synthetic, functionalized, and/or non-functionalized hydrocarbons by means of a Fischer-Tropsch process, wherein the synthesis gas is brought in contact with a suitable catalyst, and wherein water arises as a by-product, in which water a part of the synthetic hydrocarbons is dissolved. Then, in a step c), at least a part of the water produced as a by-product is fed to step a). The hydrocarbons dissolved in the water decompose into particulate carbon and hydrogen at the high temperature in step a). The carbon is converted into CO in the presence of water and at high temperature in step a). In this way, expensive purification of half of the water produced as a by-product in step b) is avoided. The expenditure for processing the product water can be reduced. The invention further relates to a plant suitable for performing the method. |
