非催化加压甲烷部分氧化制合成气

考察了非催化条件下，温度、压力和进气配比对甲烷部分氧化制合成气的影响，结果表明：甲烷的转化率随温度的升高，压力的增加，进气中氧的增加而增加；产物中合成气含量随温度的升高而增加，最高达81％以上；随着温度的升高，产物中H2／CO存在极值，在本实验的研究范围内，最大可达1．8；进气中氧增多，产物中H2／CO减小；温度升高，或压力增大，CO2的选择性也随之提高．对CO选择性的正交分析表明，进气配比对CO选择性影响最大，压力次之，温度的影响最小．

STUDY ON NO CATALYTIC PARTIAL OXIDATION OF METHANE TO SYNGAS UNDER PRESSURE

The influence of temperature, pressure, ratio of oxygen to methane under no catalyze condition to methane partial oxidation to syngas was studied. The result indicated that the methane conversion rate increases along with the temperature ascension, the pressure increase or the oxygen increase; In the product the syngas content increases along with the temperature ascension, reaches above high 81%. Along with temperature ascension, the H2/CO existence extreme value,in this experimental research scope, may reach 1.8 most greatly. With the oxygen increases to system,the H2/CO decreases. Along with the increase of temperature or/and pressure, the selectivity of CO2 increases. The carbon monoxide selective orthogonal analysis indicated that, the ratio of oxygen to methane is biggest to the CO selectivity influence, the pressure next best, the temperature influence is smallest.
