1. Способ получения синтез-газа заданного состава основных компонентов Н2 и СО в диапазоне изменения соотношения от 1: 1 до 2: 1 для производства метанола, диметилового эфира или для синтезов Фишера-Тропша автотермической каталитической конверсией природного газа, содержащего метан, углеводороды метанового ряда и примеси N2, Ar, Н2 кислородсодержащим газом, в присутствии воды (Н2О) и/или диоксида углерода (СО2), включающий две стадии:1. The method of producing synthesis gas of a given composition of the main components of H 2 and CO in the range of the ratio from 1: 1 to 2: 1 for the production of methanol, dimethyl ether or for Fischer-Tropsch synthesis by the autothermal catalytic conversion of natural gas containing methane, methane hydrocarbons a series and impurities of N 2 , Ar, H 2 with an oxygen-containing gas, in the presence of water (H 2 O) and / or carbon dioxide (CO 2 ), which includes two stages: А) смешивание природного газа с кислородсодержащим газом и сжигание углеводородов с кислородом с получением в продуктах реакции повышенного содержания Н2О и СО2;A) mixing natural gas with an oxygen-containing gas and burning hydrocarbons with oxygen to obtain a high content of H 2 O and CO 2 in the reaction products; Б) конверсию остаточного метана с продуктами горения на катализаторе,B) the conversion of residual methane with combustion products on the catalyst, отличающийся тем, что стадия (А) парциального окисления проводится в две ступени:characterized in that the stage (A) of partial oxidation is carried out in two stages: а) сверхскоростного окисления углеводородов кислородом с получением в продуктах неравновесных количеств Н2О и СН4 при мольном соотношении кислорода и метана, равном 0,6-0,7 иa) ultrahigh-speed oxidation of hydrocarbons with oxygen to obtain in products non-equilibrium amounts of H 2 O and CH 4 with a molar ratio of oxygen and methane equal to 0.6-0.7 and б) конверсии продуктов ступени (а) с корректирующими газами (СН4, СO2 или Н2О) с получением газовой смеси, которая проходит последующую каталитическую конверсию оставшегося метана водяным паром на катализаторе.b) the conversion of the products of step (a) with corrective gases (CH 4 , CO 2 or H 2 O) to produce a gas mixture that undergoes a subsequent catalytic conversion of the remaining methane with water vapor on the catalyst. 2. Способ по п. 1, отличающийся тем, что ступень (а) стадии (А) осуществляют при подаче 100% от общего требуемого расхода кислорода, (75-100%) от общего расхода исходного природного газа с получением мольного соотношения кислород:метан ≅ 0,76-0,84 и временем пребывания в зоне горения t = 0,005-0,01 с в диапазоне рабочего давления 2,0-10 МПа, при этом в получаемом газе мольная концентрация Н2О может составить от 18 до 30%, а СН4 от 1 до 8%.2. The method according to p. 1, characterized in that stage (a) of stage (A) is carried out at a supply of 100% of the total required oxygen flow, (75-100%) of the total flow of the original natural gas to obtain a molar ratio of oxygen: methane ≅ 0.76-0.84 and residence time in the combustion zone t = 0.005-0.01 s in the working pressure range 2.0-10 MPa, while the molar concentration of Н 2 О in the produced gas can be from 18 to 30% and CH 4 from 1 to 8%. 3. Способ по п.2, отличающийся тем, что ступень (б) стадии (А) осуществляют при подаче оставшейся части природного газа от 25 до 0%, корректирующего газа Н2О или СО2 с временем пребывания t = 0,003-1 с.3. The method according to claim 2, characterized in that stage (b) of stage (A) is carried out by supplying the remaining part of natural gas from 25 to 0%, corrective gas H 2 O or CO 2 with a residence time of t = 0.003-1 s .
