BIOMASS GASIFICATION PROCESS AND APPARATUS

摘要

An apparatus for a gasification of a biomass liquid solution includes a reactionchamber having a biomass liquid solution therein. The biomass solution includes at least water and carbon . A pair of spaced apart carbon electrodes are immersed in the solution within the chamber. A direct current electrical supply is connected to the electrodes to form an electrical arc passing from one electrode to the other and thereby oxidizing carbon of one electrode. The oxidized carbon forms a carbon monoxide and hydrogen gas mixture, and carbon released from the biomass solution during oxidation is deposited on the opposite electrode. A switch is interposed between the source of electric power and the electrodes so as to selectively switch the polarity of the electric arc to thereby cause oxidation of the opposite electrode and the deposit of carbon on the previously oxidized electrode while continuing to manufacture COH2 gas. A sensordetects the position of the electric arc, and thereby detects the length of the oxidizing electrode, and is electrically connected to a control unit which will cause the switch to change polarity of the electrodes when the oxidizing electrode reaches a predetermined length. The biomass solution may be formed from a mixture of water with starches, sugars, carbohydrates, alcohols, and the like.
