1. A method for gasifying solid carbonaceous fuel using gasification medium in a fixed bed pressure gasification reactor comprising a gasification medium inlet, a product gas outlet, a fuel bed of solid carbonaceous fuel arranged on an ash discharge grate, fuel supply means, ash discharge means;

  • wherein a raw synthesis gas containing hydrogen and carbon oxides is obtained, which is discharged from the fixed-bed pressure gasification reactor through the product gas outlet and subsequently processed to a pure synthesis gas, characterized in that the gasified carbonaceous liquid by-product, which is obtained in liquid form, in a form dissolved in a liquid or in a form dispersed in a liquid during the processing of the raw synthesis gas, is introduced into the gasification zone of the fixed-bed pressure gasification reactor and is likewise at least partially converted into hydrogen and/or carbon oxides; and

    at least a portion of the liquid byproducts introduced into the fixed bed pressure gasification reactor enter into;

    the gas temperature in this region is at least 700 ℃
