HYDROGEN GAS GENERATION FROM MUNICIPAL SOLID WASTE INCINERATION BOTTOM ASH AND ITS ENHANCEMENT

Abstract

 According to the results obtained in the present study, by adding scrap metal aluminum, hydrogen generation amount significantly increased. For instance, at the presence of 10% metal aluminum, hydrogen generation amount increased to more than 100m³/t-BA from 25.2m³/t-BA and existence of proper addition amount was suggested. Addition of sodium hydroxide increased hydrogen generation speed dramatically. As a result, in excess of 80% of total hydrogen was generated in the first day of the experiment. In the case of BA particle size over 4.75 mm or more, hydrogen generation amount was less than other cases. Hydrogen generation was about 40m³/t when use pilot experiment equipment. This is about 60m³/t less than previous research because of non-warming and weak agitation.
