Abstract: PROBLEM TO BE SOLVED: To avert the locally excessive distribution quantity of a promoter which may in some cases entail the deactivation of a catalyst by forming gas for propulsion, carrier gas and solid particles or liquid drops to turbulent flow and radially and uniformly distributing the formed mixture. SOLUTION: An injector constitutes double jacketed pipe consisting of an inside pipe 1 and an outside pipe 2 and this double jacketed pipe is connected to a base body 5 via an intermediate member 3 having 8 pieces of bored holes 4 with respect to the double jacketed pipe. This base body 5 is internally provided with an annular distribution chamber 51 and the connecting passage 52 in the form of the bored holes from this annular distribution chamber 51 communicates with an annular chamber 10 for the gas for propulsion to individual injector members 8 to 11 to supply the gas for propulsion through the spacing between the inside pipe 1 and the outside pipe 2 so that the carrier gas or solid particles or liquid drops supplied through the inside pipe 1 are made into the turbulent flow and the formed mixture is radially and uniformly distributed.
