Abstract:
PURPOSE: A manufacturing method is provided to offer a manufacturing method of high-yield biofuel by hydrogenation-dehydration reaction of guaiacol using bifunctional catalyst and using biomass as a source including guaiacol. CONSTITUTION: A manufacturing method of biofuel includes a stage of injecting bifunctional catalyst including reaction solution including guaiacol, metal catalyst and acid catalyst into a reactor; a stage of cleaning a reactor and inside of a pipe connected with the reactor; a stage of increasing entire pressure of hydrogen and reaction solution by injecting hydrogen into the reactor; a stage of mixing hydrogen and reaction solution; a stage of progressing hydrogenation dehydration reaction; a stage of cooling the reactor; and a stage of collecting and analyzing a created product inside of the reactor. The metal catalyst is a metal nano particle for hydrogenation. The metal catalyst is one or alloy consisting of more than two of a group consisting of Pt, Pd, Ru, Ir and Rh. The acid catalyst is an acid catalyst for dehydration, is porous or non-porous catalytic converter reacting with a metal catalyst and an acid group is present on the surface of the catalytic converter. The catalytic converter is selected more than one of a group consisting of silica-alumina complex oxide, alumina, an activated carbon, zirconia and silica. The catalytic converter is selectively formed of a group consisting of a bulk, a plate, a powder, a pellet, a ball and an aerogel. The acid group is generated after processing an inorganic acid selected from a group consisting of a nitric acid, a sulfuric acid and a hydrochloric acid. The content of the metal catalyst ranges from 0.1 to 20 weight% based on weight of the catalytic converter.

Abstract:
The present invention provides a method for producing high carbon saturated hydrocarbon from a biomass mixed solution containing benzyl phenyl ether (C_6H_5CH_2OC_6H_5) through a two phase reaction process by using a bifunctional catalyst containing an acid catalyst and a metallic catalyst. According to the present invention, a fuel to replace and supplement petroleum can be developed through decomposition and conversion of biomass containing lignin and the like, and thus a non-petroleum-based biofuel can be produced.
