The invention discloses a chilling-type method for producing synthesis gas through oxidation of a non-catalytic part of gaseous or liquid hydrocarbon. The method mainly comprises two parts including oxidation of the non-catalytic part and washing of crude synthesis gas. Gaseous or liquid hydrocarbon, an oxidant and a gasifying agent enter into a gasification chamber of a gasification furnace through a spray nozzle after being mixed according to a certain ratio to carry out oxidation of the non-catalytic part to produce synthesis gas; and high-temperature synthesis gas discharged from the gasification chamber of the gasification furnace flows through a chilling ring and a downcomer to enter into a cooling and washing chamber to be cooled and dust-removed, enters into a water scrubber after being sufficiently wetted through water replenishing, is discharged from a boundary region after being further subjected to dust removal by the water scrubber and enters into a downstream device. The method can be used for producing synthesis gas by a single gaseous or liquid hydrocarbon raw material and also treating the gaseous or liquid hydrocarbon raw material, has the advantages of wide raw material suitability, small investment, high water / gas ratio in the boundary region and the like, and is especially suitable for conversion working conditions of crude synthesis gas discharged from the boundary region.
Description
technical field [0001] The invention relates to a method for producing synthesis gas from hydrocarbon-containing materials, in particular to a method for producing synthesis gas by quenching non-catalytic partial oxidation of gaseous or liquid hydrocarbons. Background technique [0002] Natural gas, shale gas, coal bed methane, oilfield gas, refinery gas, coke oven gas, pyrolysis gas and other gaseous hydrocarbons, with methane as the main component, are important basic energy and chemical raw materials. At present, the conversion and utilization of methane can be divided into indirect conversion and direct conversion. There are only 4 symmetrical C-H bonds and high C-H bond energy (439 kJ / mol) in the methane molecule, so it has high chemical stability, which brings great difficulties and challenges to the conversion and utilization of methane. Production of synthesis gas (CO+H) from gaseous hydrocarbons 2 ) is a commonly used method for the indirect conversion of methane....
