WebFeb 11, 2024 · Higher feed temperatures were required to achieve a “light off” of the PBR, while the CSTR required considerably lower feed temperatures to reach nearly comparable conversions. The CSTR—a fluidized bed in likely practice—favored synthesis gas production over C 2+ H x as compared to the PBR. WebMoving bed reactors are catalytic reactors in which the catalyst moves through the reactor along with the reactants. They are open systems and operate at a steady state.
