The invention relates to a method for the direct thermochemical conversi-on of high molecular weight organic starting products into low molecular weight organic products that are liquid with a low viscosity at ambient temperature and can be combus-ted. Said method consists of the following steps : (1) the starting product, at least one re-ducing gas and slow-evaporating product fractions are provided in a reactor, (2) the provided starting material is rapidly heated to a reaction temperature, (3) said starting mate-rial is converted using the temperature, the reducing effect of the gas and autocatalytical effects of the product fractions in vaporous reaction products and reaction gas, (4) the re-action gas is separated by means of condensation by evacuating the condensed reaction products, said separated reaction gas comprising a mixture of hydrogen, methane and other hydrocarbons and carbon monoxide and carbon dioxide. Said claimed method is characterised by other additional steps : (5) the separated reaction gas is conditioned by discharging at least one part of the gas mixture and optionally, introducing hydrogen, said conditioning followed by (6) re-injecting the conditioned reaction gas into the reac-tor for simultaneously producing a hydrating, reducing and stripping effect for converting the starting material. According to the invention, the amount of active gas fractions and its part in the total flow of the reaction gas can be modified in an advantageous manner, thus increasing the effectiveness of the method and leading to an improvement of the tar-get product quality and yield with total lower production costs. The invention also relates to a method for carrying out the claimed method.
