Apparatuses and processes that produce multimodal polyolefins, and in particular, polyethylene resins, are disclosed herein. This is accomplished by using two reactors in series, where one of the reactors is a multi-zone circulating reactor that can circulate polyolefin particles through two polymerization zones optionally having two different flow regimes so that the final multimodal polyolefin has improved product properties and improved product homogeneity.

A chemical reaction apparatus includes: a horizontal flow-type reactor inside of which has been partitioned into multiple chambers by multiple partition plates, and a liquid content horizontally flows with an unfilled space being provided thereabove; a microwave generator that generates microwaves; and at least one waveguide that transmits the microwaves generated by the microwave generator to the unfilled space in the reactor. The content flows over each of the partition plates, and, in each chamber, a weir height on an inlet side is higher than a weir height on an outlet side by at least an overflow depth at the partition plate on the outlet side.

A reactor and its internals used for the thermal processing of a mixture. The reactor comprises plates and at least part of the surface of said plates is used to perform said thermal processing. The reactor and its internals are used for the thermal processing of mixtures containing organic compounds. The processes, for thermal processing a mixture comprising organic compounds, comprising the steps of feeding the reactor and its internals and being useful for treating wastes oils and/or for destroying hazardous and/or toxic products; and/or for reusing waste products in an environmentally acceptable form and/or way, and/or for cleaning contaminated soils or beaches, and/or cleaning tar pits, and/or use in coal-oil co-processing, and/or recovering oil from oil spills, and/or PCB free transformed oils. A process for fabricating the reactor and its internals is also proposed.

Chemical reactors with annularly positioned delivery and removal devices, and associated systems and methods. A reactor in accordance with a particular embodiment includes a reactor vessel having a light-transmissible surface proximate to a reaction zone, and a movable reactant delivery system positioned within the reactor vessel. The reactor can further include a product removal system positioned within the reactor vessel and positioned annularly inwardly or outwardly from the delivery system. A solar concentrator is positioned to direct solar radiation through the light-transmissible surface to the reaction zone.

The support mechanisms of the present invention comprise a vessel supported by suspension cables suspended from trollies that can move along the length (longitudinal) of a framework. The support system is such that waste material, even upon heating, cooling, etc., can constantly and smoothly move through the entire system, with the vessel generally being in a natural, balanced orientation.

A manufacturing facility (12) is provided. The manufacturing facility (12) includes one or more interconnectable modules (10). At least one of the one or more interconnectable modules (10) includes a housing (14) and a reactor (16) in the housing (14). The housing (14) has at least one charging inlet (18) and at least one discharging outlet (20). The reactor (16) has at least one reactor inlet (22) coupled to the at least one charging inlet (18) of the housing (14) and at least one reactor outlet (24) coupled to the at least one discharging outlet (20) of the housing (14).
