PROCESS FOR PRODUCING ACTIVATED CARBON

摘要

PURPOSE: A method for manufacturing activated charcoal is provided to save costs required for refining bio gas and to simplify a bio gas refining process by simultaneously eliminating hydrogen sulfide and siloxane which are byproducts of the bio gas. CONSTITUTION: A method for manufacturing activated charcoal includes the following: the surface of wood-based raw materials is activated by keeping temperatures in a range between 800 and 900 degrees Celsius and applying vapor to the materials for a pre-set period of time(S1); and the temperature of the surface activated raw materials is kept in a range between 400 and 500 degrees Celsius, and oxygen is applied to the materials for a pre-set period of time to form oxygen-containing functional groups at the materials(S2). The wood-based raw materials are coconut shell powder.
