Patent ID: 8333927

Claim:
A hole-jetting type reactor, comprising: an internal feed tube; an external feed tube coaxial with the internal feed tube, the external feed tube having two ends, wherein the internal feed tube and the external feed tube define an annular space therebetween, and wherein the two ends of the external feed tube are closed; a convergent channel coaxially connected to a downstream part of the internal feed tube; a necking tube coaxially connected with the convergent channel, wherein the cross sectional area of the necking tube is less than that of the internal feed tube; a divergent channel coaxially connected to the downstream part of the necking tube; a reaction tube coaxially connected with the divergent channel, wherein the cross sectional area of the reaction tube is greater than that of the necking tube; and 2 to 20 holes in the wall of the downstream part of the internal feed tube or in the wall of the convergent channel, wherein part or all of the holes are arranged at the same cross section of the internal feed tube or the convergent channel, and wherein the cross section is perpendicular to the flow direction of a reactant in the internal feed tube, and distributed symmetrically, and wherein the cross sectional area of the holes totals 2% to 30% of the cross sectional area of the internal feed tube.
