A two-step thermochemical reactor and method are disclosed. The reactor includes a housing and a reactor cavity formed within, and surrounded by, thermal insulation within the housing. The reactor cavity includes at least one unit cell, each cell having an electric heat source and a reactive material. The reactor also includes a feedstock inlet and a product outlet in fluid communication with the reactor cavity. The reactor also includes a reducing configuration, with the inlet being closed and the electric heat source of each unit cell being driven to thermally reduce the reactive material at a first temperature, releasing oxygen into the cavity. The reactor also has a splitting configuration where the reactive material is at a second temperature that is lower than the first, the feedstock inlet open and introducing feedstock gas into the cavity to reoxidize the reactive material and split into a product gas.

This disclosure relates to systems and processes for cooling polymer product mixtures manufactured at high pressure. The processes of the invention involve cooling and then subsequently reducing the pressure of the product mixture from the reactor. In the systems of the invention, a product cooler is located downstream of the high pressure reactor and upstream of a high pressure let down valve.

A box style steam methane reformer (15) has plural sections (37), with each section having walls (27-29-31, 33) forming an interior cavity (35) and open ends (43) that communicate with the interior cavity. Each section has a feedstock supply pipe (71) and a fuel supply pipe (63) located along the top wall, as well as a syngas collection pipe (79) and a flue gas collection duct (75) located outside of the bottom wall. The pipes and ducts have ends that are aligned with each other to allow the sections to be assembled together. Burners (67) are in the interior cavity and are connected to the fuel supply pipe. Reactor tubes (59) extend through the interior cavity. Refractory members (81) are located in the interior cavity and across a slot. The spacing between the refractory members varies to control the flow of flue gas.
