Patent ID: 8206652

Claim:
A jet reactor, comprising: an internal feed tube, an external feed tube coaxial with the internal feed tube, and an annular space defined between two said feed tubes, wherein both ends of the external feed tube are closed; a reaction tube coaxially connected to the downstream of the internal feed tube, jet holes made in the wall of the downstream part of the internal feed tube and the jet holes are connected with flow ducts, wherein said jet holes and said flow ducts are connected in a smooth transition manner, and the numbers of said jet holes and said flow ducts connected thereto are 2-20 respectively, wherein outlets of flow ducts are positioned at a first suppositional circle coaxial with the internal feed tube and symmetrically arranged at the first suppositional circle, and the diameter of said first suppositional circle is 0.1 to 0.99 times of the inner diameter of the internal feed tube, wherein the flow direction of a feedstock at outlets of flow ducts is tangent with a second suppositional circle defined by the center of jet holes, the center of outlets of flow ducts and the axis of the internal feed tube; and wherein flow ducts are engineered to be a curve shape, and the curve shape is overlapped with the second suppositional circle.
