Hydrogen Generation MA31W203 吳俊儀

Partial Oxidation process can be used to produce hydrogen from heavy hydrocarbons such as diesel fuel and residual oil. Any hydrocarbon feedstock that can be compressed or pumped may be used in this technology.

Complete oxidation : partial oxidation : Takeing Methane for example :

Hydrocarbons Vapor Oxygen Air Preheater Burner Absorption Tower Hydrogen(97%) Purifier Remove acid gas system Converter

methane and other hydrocarbons in natural gas are reacted with a limited amount of oxygen (typically, from air) that is not enough to completely oxidize the hydrocarbons to carbon dioxide and water. CH4 + ½O2 → CO + 2H2 (+heat) Exothermic reaction (heat is evolved)
