Abstract

MgO is extensively used for various applications. A Venturi jet reactor can help prepare the micro- or nano-sized magnesia via pyrolysis. However, the reactors have an uneven mixing and concentration distribution. The operational and structural parameters of the reactor have therefore been optimized to overcome this issue. The numerical simulations indicate that higher flow rates of MgCl2 at the inlet yield higher reactor temperatures and higher MgO product concentrations. The ideal diameter ratio between the straight tube and the throat of the reactor is 5/2 with an angle between the draft tube and the throat of 90° and a draft pipe with a diameter of 25 mm. Our results provide data support for the design optimization of pyrolysis reactors.
