A clustered reaction system includes multiple reaction devices, a cooling device and a gas supply device. Each of the reaction devices includes a reaction tank unit defining a reaction space, multiple through holes extending through the reaction tank unit, a heat exchange module including a heat exchange passage surrounding the reaction tank, and an injection module extending through one of the through hole. The cooling device is connected to the heat exchange passages of the reaction devices for supplying a coolant into the heat exchange passages. The gas supply device is communicated fluidly with one of the through holes of each of the reaction devices for supplying a gas to the reaction devices.

Disclosed herein are processes and reaction systems for controlling a temperature of an oligomerization reaction zone using a heat exchange system.

A continuous flow process and system for depolymerizing plastic. A heterogeneous mixture of solid plastic particles, a solvent, and a catalyst are pumped continuously through a heating zone at a flow rate resulting in a particle speed sufficient to keep the plastic particles in suspension. The heterogeneous mixture is heated in the heating zone and maintained in a hold zone to complete depolymerization of the mixture into a homogeneous solution containing a liquefied reaction product. The homogeneous solution is cooled to solidify and precipitate a solid reaction product. The solid reaction product is separated from the solvent to be recycled. Contaminants are removed from the solvent, and the solvent is recirculated for use as a constituent of the heterogeneous mixture.
