Abstract
A novel process of producing gas fuel is provided, in which low quality fuel such as coal and various kinds of plastics and resins (polymeric compounds) collected as flame retardant waste are decomposed to gas in supercritical water, so that the resultant gas is effectively utilized as fuel. That is, polymeric compounds and aromatic/condensed-aromatic hydrocarbons are decomposed in supercritical water with ruthenium oxide (IV) as a catalyst. The resultant gas components through the decomposition are collected as gas fuel.
Claims3
A method of producing gas fuel, comprising:
- decomposing a polymeric compound or an aromatic/condensed-aromatic compound in supercritical water with ruthenium oxide (IV) as a catalyst, and
- collecting gas generated from the decomposition as the gas fuel.
A method of producing gas fuel, comprising:
- immersing a polymeric compound or an aromatic/condensed-aromatic compound in supercritical water as a material to be processed for obtaining the gas fuel,
- reacting the material to be processed in the supercritical water with ruthenium oxide (IV) as a catalyst to decompose the material to be processed into a gas component and an organic residue, and
- collecting the gas component as the gas fuel.
