Fluid mixing and distribution device for a downflow catalytic reactor, the said device comprising a mixing zone comprising at least one fluid-mixing space of length L1′ and a fluid-exchange space of length L2′, situated underneath and superposed with said mixing space, it being understood that the length L2′ of the said exchange space is strictly greater than the length L1′ of the said mixing space so as to create a roof at the level of the said exchange space, the said roof comprising at least one longitudinal opening suited to the passage of the following its from the said exchange space to the said distribution zone.

The invention provides an improved system for separation technology intended to reduce unwanted catalyst/thermal reactions by minimizing contact of the hydrocarbons and the catalyst within the reactor.

Gas injectors for providing uniform flow of fluid are provided herein. The gas injector includes a plenum body. The plenum body includes a recess, a protrusion adjacent to the recess and extending laterally away from the plenum body, and a plurality of nozzles extending laterally from an exterior surface of the plenum body. The plenum body has a plurality of holes in an exterior wall of the plenum body. Each nozzle is in fluid communication with an interior volume of the plenum body. By directing the flow of fluid, the gas injector provides for a uniform deposition.

A reactor for accommodating high contaminant feedstocks includes a reactor vessel having an inlet for introducing a feedstock containing contaminants into an interior of the reactor vessel. A basket is located within the reactor vessel interior and contains a particulate material for removing contaminants from the feedstock to form a purified feedstock that is discharged to a purified feedstock outlet. A catalyst is located within the reactor vessel and in fluid communication with the purified feedstock outlet of the basket for contacting the purified feedstock to form a desired product.

In one embodiment, a reactor includes a reactor body and a reactor head. The reactor head has a reactor head body and one or more inlets disposed tangentially to the reactor head body. In one embodiment, a polymerization process for forming polymer includes introducing in a first direction a stream including a monomer. The stream and a catalyst system are flowed in a second direction through at least one internal heat exchanger. The second direction is substantially orthogonal to the first direction. The reaction zone includes at least one internal heat exchanger. At least a portion of the monomer of the stream is polymerized in the reaction zone to produce a polymer product. The polymer product is recovered from the reaction zone.
