    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.

    Abstract: A jet injector finely distributes solid or liquid particles over a large area e.g. the use of silver with promoter as a catalytic material in the manufacture of formaldehyde. The injector has two or more single injectors secured to a base (5, 7) and a double mantled pipe (1, 2). The base (5, 7) is joined to and sealed with the double mantled pipe (1, 2) and has link apertures (70) between the inner space within the pipe (1) and the injector (8, 9, 10, 11) inner guide (11). It also has link passages (52) linking the zone between the double mantle pipe inner pipe (1) and the outer pipe (2), and an outer guide (8, 9) surrounding the inner guide (11). The base (5, 7) and individual injectors (8, 9, 10, 11) produce a mixture of carrier gas and aerosol charge of droplets or solids passing between the inner (1) and outer (2) pipes (1), and a uniform radial expansion of the mixture.

    Abstract: Particulate olefin polymers are prepared by catalytic polymerization of monoolefins in an auxiliary liquid containing the monomers to be polymerized in dissolved form and the particulate polymer product in suspended form. The reaction mixture is recycled in a loop to which the starting materials are fed and from which the particulate polymer formed is removed. The essential features are (a) that a side stream is branched off from the loop, (b) that the side stream is caused to pass through a separating zone in which particulate olefin polymer is separated by centrifugal acceleration at temperatures and pressures in the same range as present in the loop and (c) that the separated particulate olefin polymer is discharged through flashing means.
