An alternative method for the production of second-generation biofuels†
Abstract
Direct coal liquefaction (DCL) is an industrial technology for the production of liquid fuels by high-pressure and high-temperature hydroconversion of coal. The technique can also be applied to biocoals produced by hydrothermal carbonization (HTC) of biomass waste. The biofuels produced are promising with regard to the H/C molar ratio, higher heating value and oxygen content.
