Method for producing SNG or SYN-gas from wet solid waste and low grade fuels

摘要: Peat, lignite, coal, many forms of biomass (land or marine) and solid wastes may have from 1/2 to 30 times as much water associated with the dry solids. Some this be chemically bound otherwise practically inseparable by mechanical means. The solids partially oxidized oxygen air in first chemical reactions a Wet Air Oxidation (WAO) taking place presence large amount at temperatures 175° C. 325° pressures 10 100 atmospheres--preferably 240° 300° 70 atmospheres.
