Conversion of liquid combustible wastes in the filtration regime to syngas by partial oxidation

Abstract

A new method of combustion/conversion of liquid combustible wastes is proposed in the filtration mode when one of the reagents (liquid fuel or oxidizer gas) is supplied from the end of the reactor filled with a porous incombustible backfill (inert) and the other into the middle part. In this case, the inert, charged to the upper part of the reactor at room temperature, is heated in countercurrent combustion products. At discharging of inert from the lower part of the reactor (and the equal volume is simultaneously added to the upper part, so that the bed in the reactor is kept constant), the inert heated in the upper part enters the lower part, where it gives heat to the gaseous reagent supplied from below. This method can be carried out both with an excess of the oxidant with the combustion of combustible liquids to CO2 and H2O, and with a lack of oxidizer, when the conversion of the initial fuel to the synthesis of a gas predominantly containing CO and H2 takes place. On the example of a model fuel (isopropyl alcohol), the regularities of filtration combustion at different oxidant to fuel ratios have been experimentally studied.
