摘要
作为烃类液化的最重要步骤,从天然气制合成气是近几十年催化科学研究的前沿和热点之一。结合笔者实验室的工作,本文介绍了国内外甲烷临氧催化转化制合成气的研究现状,对甲烷部分氧化、甲烷临氧二氧化碳重整、甲烷临氧水蒸气重整及甲烷-二氧化碳-水-氧气偶合重整进行了阐述和分析,综述了在催化剂体系、反应机理和工艺条件等方面近期取得的研究成果;并对甲烷临氧催化转化制合成气技术今后的研究重点及应用作了展望。
The preparation of synthesis gas from natural gas, which is the most important step in the gas-to-liquid transformation, has attracted increasing attention in the last decade. The varieties of synthesis gas technology by catalytic converting methane in the present of oxygen are introduced briefly. Authors＇ work in preparation of syngas form methane in the presence of oxygen is referred. The various processes including catalytic partial oxidation （CPO）, auto-thermal CO2 reforming （ ATR-CO2 ）, auto-thermal H20 reforming （ ATR-H2O） and tri-reforming of methane are reviewed. Achievements including catalyst, reaction mechanism and process conditions are discussed. The research focus and commercial application of catalytic converting methane in the future are also prospected as well.
