FIELD: process engineering.
SUBSTANCE: invention relates to production of synthesis gas. Proposed method comprises the steps that follow. Hydrocarbon reforming in the presence of steam and one and more catalysts in the first reaction zone to obtain exit flow containing part of hydrocarbon, carbon monoxide, carbon dioxide and hydrogen at first temperature. Note here that said first reaction zone can included one or more tubes with catalyst. In includes indirect heating of exit flow from first temperature to second temperature. Reforming of exit flow is performed at second temperature in the presence of one or more oxidisers and one or more second catalysts under conditions sufficient for production of synthesis gas with temperature of about 1030°C or higher. Said flow contains hydrogen, carbon monoxide, carbon dioxide and less than about 5 mol % of methane per dry substance. Note here that synthesis gas is used for indirect heating of exit flow from first temperature to second temperature.
EFFECT: power savings.
