天然气是大规模生产许多化学品（例如甲醇和合成燃料）的主要原料，无论是使用TIGAS工艺生产汽油还是使用费托合成法生产柴油。人们对将天然气直接转化为最终产品的工艺开发进行了大量研究。然而，当今和未来几年最经济的路线是分两个阶段的工艺，第一步是合成气生产。生产合成燃料和化学品中资本和能源最密集的方面是合成气生产。本文对合成气规模化生产的关键技术进行了概述和比较。我们发现，在生产甲醇和合成燃料的工厂中，低蒸汽碳比的自热重整是最经济、最有效的合成气生产技术。
Natural gas is the dominant feedstock for large-scale production of many chemicals, such as methanol and synthetic fuels, either using the TIGAS process to produce gasoline or using Fischer-Tropsch synthesis to produce diesel. Significant research has gone into the development of processes that convert natural gas directly into the end product. However, the most economical route today, and in the years to come, is a process in two stages with synthesis gas production as the first step. The most capital- and energy-intensive aspect of producing synthetic fuels and chemicals is synthesis gas production. This paper outlines and compares key technologies for large-scale production of synthesis gas. We find that auto-thermal reforming at a low steam-to-carbon ratio is the most economic and efficient technology for synthesis gas production in plants both for producing methanol and synthetic fuels.
