Mixture gas catalytic deoxidation process containing combustible gas
2008
The invention discloses a catalysis deoxidation process for mixed gas containing inflammable gas. In a reaction system, the inflammable gas in the mixed gas raw material is reacted with oxygen in a catalysis reactor filled with catalyst for deoxidation, and the catalysis reactor comprises a plurality of heat insulation reactors connected in series, wherein the last heat insulation reactor is the main reactor; the mixed gas raw material entered from the first heat insulation reactor is mixed with circulating gas and preheated before entering; and the mixed gas raw material entered from other reactors can directly enter or be mixed with the circulating gas and enter the reactors without preheating. The invention can also be realized in another mode, namely a plurality of reactors connected in series are superimposed to form a multi-layer reactor. The process greatly reduces the consumption of the circulating gas, and achieves the effects of reducing the consumption of catalyst, reducing the sizes of a circulator, a heat exchanger and a pipe, lowering cost, reducing the energy consumption of the circulator and cooling water, increasing byproduct vapor and so on.
