TECHNOLOGY FOCUS - CHEMICAL ENGINEERING - Preferred Method: In producing biofuel, the additional catalyst is an additional base catalyst, where the additional base catalyst is an alkali metal hydroxide catalyst or a transition metal hydroxide catalyst. The additional base catalyst is sodium hydroxide or potassium hydroxide. Treating is performed under conditions of continuous flow. It comprises use of at least one additional catalyst that enhances incorporation of hydrogen into the organic matter. The catalyst that enhances incorporation of hydrogen is selected from alkali metal formate catalysts, transition metal formate catalysts, reactive carboxylic acid catalysts, transition metal catalysts, sulfide catalysts, noble metal catalysts, water-gas-shift catalysts, and its combinations. Preferably, the catalyst is sodium formate. Treating comprises use of at least one additional catalyst that enhances removal of oxygen from the organic matter. The catalyst that enhances removal of oxygen from the organic matter is selected from acid catalysts, transition metal catalysts, noble metal catalysts, supported transition metal catalysts, solid acid catalysts, and its mixtures. The organic matter is fossilized organic matter having a carbon content of at least 50%, and the aqueous solvent is water. The temperature is between about 320 degrees C and about 360 degrees C, and the pressure is between about 200 bar and about 250 bar. Fossilized organic matter is lignite, the temperature is between about 340 degrees C and about 360 degrees C, and the pressure is between about 200 bar and about 240 bar. The biofuel comprises one or more of an oil component, a char component and a gaseous component comprising methane, hydrogen, carbon monoxide and carbon dioxide. Organic matter is lignocellulosic matter, and the aqueous solvent comprises alcohol. The lignocellulosic matter comprises more than about 10% of each of lignin, cellulose, and hemicellulose. Temperature is between about 270 degrees C and about 360 degrees C, the pressure is between about 170 bar and about 250 bar, and the solvent comprises between about 5% and 40% alcohol by weight. Temperature is between about 300 degrees C and about 340 degrees C, the pressure is between about 200 bar and about 240 bar, and the solvent comprises between about 10% and about 30% alcohol by weight. The alcohol is ethanol. Treating is for a time period of between about 20 minutes and about 30 minutes. The method comprises the step of heating the organic matter and aqueous solvent to the temperature in a time period of less than about 2 minutes prior to the treating. It comprises the steps of: (i) cooling the organic matter to a temperature of between about 160 degrees C and about 200 degrees C in a time period of less than about 30 seconds after the treating; and (ii) depressurization and cooling the organic matter to ambient temperature by release through a pressure let down device. The biofuel comprises an oil component having a gross calorific value of more than 35 MJ/kg. Biofuel comprises an oil component having greater than about 8% wt db hydrogen and less than about 10% wt db oxygen. EXAMPLE - No suitable example given.
