SYSTEM FOR REFORMING BIOGAS USING WASTE HEAT, AND METHOD FOR REFORMING BIOGAS USING SAME

摘要

The present invention relates to a system for reforming biogas using waste heat and to a method for reforming biogas using the system. In detail, the system for reforming biogas includes: 1) a gas engine using biogas as a main fuel; 2) a heat exchanger recovering heat from the exhaust gas of the biogas engine in order to increase the temperature of the reforming biogas; and 3) a reformer feeding the reforming biogas into the biogas engine after the reforming biogas heated by means of the heat exchanger is catalytically reformed using a synthesis gas containing hydrogen.
