由天然氣製造液體油料－ＧＴＬ製程之發展潛力及經濟性
Production of liquid fuels from natural gas-Potential progress in GTL and its economics
摘要
構成GTL製程的關鍵技術，Fischer-Tropsch合成反應，幾十年來已是世人熟知的技術，該項技術最初被用於由煤製造液體燃料或化學品，但是歷經多年的研究改進，GTL各單元包括合成氣製備、F-T反應器設計、產品精煉等技術皆有明顯進展，使得天然氣作為GTL進料更具經濟性。由於GTL製程生產的高品質汽、柴油能符合2006年嚴苛的燃油規範，預期未來數年利用GTL製程生產的液體燃料將獲得快速的成長，此舉將對石油、石化、農業、環保、及能源等產業產生重大衝擊。本文針對GTL製程近年來的技術演進、未來發展潛力、及其經濟性提出詳細說明。

The main step in the production of liquid fuels and chemicals through gas-to-liquids(GTL) process, the Fischer-Tropsch(F-T) reaction pathway, has been known for over several decades. Initially, the technology was applied for converting coal-based feedstocks into liquid fuels. Over the years, however, the technology has witnessed significant improvements in the production of syngas, in F-T reactor design, and in the product-upgrading technology enabling the use of natural gas feedstocks economically. Therefore, the use of GTL for chemicals and energy production is expected to make a rapid progress in the next few years when stringent environmental legislation is to be enforced. Potential progress in GTL process and its economics will be discussed in this article.
