Abstract: Techniques are provided for catalyst preparation. A system for catalyst preparation may include an agitator disposed inside a polymerization catalyst tank and configured to mix a polymerization catalyst and a solvent to generate a polymerization catalyst solution. The system may also include a heating system coupled to the polymerization catalyst tank and configured to maintain a temperature of the polymerization catalyst solution above a threshold. The system may also include a precontactor configured to receive feed streams comprising an activator and the polymerization catalyst solution from the polymerization catalyst tank to generate a catalyst complex. The system may also include a transfer line configured to transfer the catalyst complex from an outlet of the precontactor to a reactor.

Abstract: The invention relates to an injection device (10) configured to atomize a liquid into droplets using a gas, comprising a hollow tubular body (12) of longitudinal direction (X). An internal wall (13) defines a first zone referred to as a contact zone (Z1) and a second zone (Z2). The body has: at least a first and a second inlet opening (14; 16) opening into the said first zone (Z1), so as to respectively inject a liquid and an atomizing gas, at least one outlet orifice (18) situated downstream of the first and second zones, for removing the atomized liquid from the body. The internal wall (13) of the body is provided, between the zones (Z1) (Z2), with at least one chicane (20i) configured so that, in each plane perpendicular to the longitudinal direction of the body containing the said chicane, this chicane extends over just part of the periphery of the internal wall (13).

Abstract: The present invention provides a feed gas feeding system for a propylene ammoxidation reactor. The feed gas feeding system comprises a feed gas mixing system and a feed distributor. A propylene and ammonia mixed gas is mixed by the feed gas mixing system and then uniformly distributed in the propylene ammoxidation reactor by means of the feed distributor, an initial temperature T0 when the propylene and ammonia mixed gas enters the feed distributor being 10-220° C. The propylene and ammonia feed gas feeding system of the present invention for ammoxidation of propylene and the preparation of acrylonitrile prevents the temperature of a gas mixture at any position in the propylene and ammonia feed distributor from reaching a temperature at which ammonia decomposes into active nitrogen atoms, thereby reducing a risk of brittle nitriding fractures of the propylene and ammonia distributor.
