METHOD AND APPARATUS FOR PRODUCING ELEMENTARY SULFUR AND MOLECULAR HYDROGEN Russian patent published in 1997 - IPC

FIELD: conversion of hydrogen sulfide into elements. SUBSTANCE: initial acid gas mixture is heated and exposed to directed microwave radiation, vector diagram of field coinciding with displacement vector of initial mixture. Phase separation of dissociation products and their withdrawal from reaction zone is accomplished by way of changing direction of displacement of initial mixture and dissociation products at reaction zone outlet. Reactor for conducting radical-chain non-branched reaction of hydrogen sulfide decomposition contains casing with initial mixture-supply chambers, heating chamber, chamber for removing gaseous products, elementary sulfur collection and cooling chamber, and microwave radiation absorption chamber. EFFECT: enhanced efficiency of process. 10 cl, 2 dwg
