FIELD: conversion of liquid paraffin-containing hydrocarbon including stage of partial burning of mixture of liquid hydrocarbon with gas containing molecular oxygen in reaction chamber in presence of catalyst maintaining combustion above normal limit of ignitability at producing flow of products and hydrocarbon ratio in reaction chamber. SUBSTANCE: process is conducted at stiochiometric relationship between hydrocarbon and oxygen exceeding stoichiometric relationship required for complete combustion to carbon dioxide and water at periodic replacement of liquid hydrocarbon and gas containing molecular oxygen by flow of hydrocarbon-containing gas enriched with fuel during period of time sufficient for removal of considerable amount of hydrocarbon sediment from reaction chamber. EFFECT: facilitated process. 15 cl, 4 tbl, 3 ex
