TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Catalyst: The hydrolyzing catalyst is selected from heat and/or an acid (preferably carbonic acid, acetic acid, formic acid, nitric acid, or sulfuric acid). The catalyst employed in step (c) is a supported metal catalyst, where the metal is selected from molybdenum, nickel, cobalt, rhodium and/or platinum.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: The process involves employing in step (c) at least a portion of the hydrogen produced in step (b). In the process, the lignocellulosic feedstock is reduced prior to hydrolyzing to a particle size of less than 2 mm in its smallest dimension, where the lignocellulosic feedstock is purified prior to hydrolyzing. In the process, the hydrolyzing catalyst comprises heating the feedstock to 170-300 degrees C. In the process, the hydrolyzing catalyst comprises an acid having a pH of less than 4. In the process, the lignocellulosic hydrolyzate is in a substantially liquid to fully liquid form or in a substantially solid to fully solid form. In the process, the treating comprises steam reforming, autothermal reforming, and anaerobic digesting. In the process, the hydrolyzing is conducted in the presence of water, alcohol, and carbon dioxide. The process further involves neutralizing the lignocellulosic hydrolyzate before treating. The process is conducted in the absence of neutralizing the lignocellulosic hydrolyzate. The process involves reacting the entire hydrolyzate residue with hydrogen in the presence of a catalyst to obtain an energy source. The process further involves deoxygenating the hydrolysate residue, where the amount of hydrolyzate residue formed in step (a) is 30-55 mass.% based on the initial weight of the lignocellulosic feedstock. In the process, the hydrolyzate residue of step (a) comprises 90 wt.% Mason lignin based on the total weight of hydrolyzate residue. The process for producing an energy source involves: (a) hydrolyzing a lignocellulosic feedstock in the presence of water, alcohol, and carbon dioxide at 220-290 degrees C to form a first mixture comprising lignocellulosic hydrolyzate and a hydrolysate residue; (b) reforming the lignocellulosic hydrolyzate to produce a second mixture comprising hydrogen; (c) reacting at least a portion of the hydrolyzate residue of the first mixture with at least a portion of the hydrogen produced in step (b) in the presence of a catalyst to obtain an energy source. The process further involves converting the energy source of step (c) to a fuel suitable for transportation. Preferred Energy Source: The liquid energy source comprises (wt.%) oxygen (20-25), carbon (70-78), and hydrogen. EXAMPLE - Sample of yellow pine (30 g) was ground and placed in a stirred reactor with water. The reactor was sealed, pressurized with CO2, and heated to 180 degrees C. The reactor reached a pressure of 1000 psig and was held at 180 degrees C for 30 minutes. After cooling, the hydrozylate was separated from the hydrolysis residue by filtration. Portions of the hydrozylate and hydrolysis residue were analyzed. The hydrolysis residue was subjected to a second hydrolysis in which water, ethanol, and CO2 were present. After the second hydrolysis step the hydrolysis residue was found to hydrozylate. The hydrozylate was fed to a stream reforming reactor loaded with 0.5 wt.% rhenium catalyst on alumina. For the first 2 hours the system was operated as an autothermal reformer with air flow gradually being reduced. After 2 hours the air flow was turned off and the reactor was operated as a steam reformer to obtain hydrogen product.
