<p>PROBLEM TO BE SOLVED: To secure a reaction having high selectivity and conversion by providing a source of a 1st gaseous reactant having a specific temp., a mixing chamber, where the reaction does not occur, and a reaction zone, where suffers the gas phase reaction in a reaction device, in the case of forming a uniform gaseous reactant mixture by reacting the 1st gaseous reactant with a 2nd gaseous reactant in the reaction device. SOLUTION: The 1st component in the reaction device is the source of the hot gaseous reactant (reactant A) having a temp. higher than 500 deg.C. The reactant A is injected to a mixing chamber of the reaction device as expansion jet. The expansion jet can be formed by providing an adjuster (such as a flow nozzle) between the hot gas source and the mixing chamber. The 2nd gaseous reactant (reactant B) in one of a gaseous state and a super critical state is injected near a place, where the reactant A is injected. In the mixing chamber, the reactant A and the reactant B does not react with each other substantially, though rapidly mix with each other. Next, the mixture of the reactant A with the reactant B is subjected to gas phase reaction in the reaction zone.</p> |
