Abstract
A new method for the partial oxidation of methane in a rapid compression machine with internal heat recovery was proposed and examined. A rapid compression machine on the basis of an internal combustion engine with a cylinder divided by a partition with a crossflow orifice into two chambers was considered. Internal heat recovery was implemented using a thermal activator installed in the smaller (auxiliary) chamber. Calculations demonstrated that this method makes it possible to convert methane in methane-air mixtures with a hydrocarbon content of up to 24% at degrees of compression of 10 to 20 and peak pressures below 200 atm. A region (determined by the crossflow orifice diameter and degree of compression) within which a heat recovery cycle exists was revealed. It was demonstrated that, for mixtures containing 22% methane or less, the extent of conversion exceeds 93%, a value that makes it possible to generate useful energy at degrees of compression above 10.
