The invention relates to a jet spouted bed reactor, comprising a cylindrical area, a gas injection pipe at the base of the cylindrical area, and a transition area, connecting the upper end of the pipe to the base of the cylindrical area, this transition area having a convex profile in a plane extending through the axis (YY′) of flow of a fluid in the pipe. 1. Jet spouted bed reactor , comprising a cylindrical area , a gas injection pipe at the base of the cylindrical area , and a transition area , connecting the upper end of the pipe to the base of the cylindrical area , this transition area having a convex , or predominantly convex , profile in a plane extending through the axis (YY′) of flow of a fluid in the pipe.2. Jet spouted bed reactor according to claim 1 , in which the angle β between the axis of flow of a fluid in the pipe and the tangent to the convex claim 1 , or predominantly convex claim 1 , profile at the point where it joins the pipe is at least equal to 5° claim 1 , and claim 1 , preferably claim 1 , less than 45°.3. Jet spouted bed reactor according to the preceding claim claim 1 , the angle β being at least equal to 10° claim 1 , and claim 1 , preferably claim 1 , less than 35°.4. Jet spouted bed reactor according to claim 1 , the convex or predominantly convex profile having a point of inflexion claim 1 , and the angle θbetween claim 1 , on the one hand claim 1 , an axis perpendicular to the direction of flow of a fluid and extending through the base of the cylindrical part and claim 1 , on the other hand claim 1 , the tangent to the point of inflexion I of the convex profile claim 1 , being greater than 10°.5. Jet spouted bed reactor according to claim 1 , wherein the angle θbetween claim 1 , on the one hand claim 1 , an axis perpendicular to the direction of flow of a fluid and extending through the base of the cylindrical part and claim 1 , on the other hand claim 1 , a straight line extending through the end of the gas injection pipe and ...
