Transient isotopic tracing is applied to Fischer-Tropsch and related syntheses producing hydrocarbons and oxygenated compounds. These reactions furnish the basic path for production of carbon compounds from coal. Previous work has applied this method to methanation over nickel, molybdenum sulfide, and ruthenium and has identified the key surface intermediates. This work aims to illustrate how these one-carbon intermediates react with each other as well as with hydrogen and with carbon monoxide to form simple hydrocarbons and oxygenated species of higher molecular weight. Ruthenium catalysts are employed. It is known that a large variety of compounds are produced in this system; this work should provide the knowledge needed for control of conditions to maximize production of desired species.

瞬态同位素示踪适用于生产碳氢化合物和含氧化合物的费托合成和相关合成。 这些反应提供了从煤生产碳化合物的基本途径。 先前的工作已将该方法应用于镍、硫化钼和钌的甲烷化，并确定了关键的表面中间体。 这项工作旨在说明这些一碳中间体如何相互反应以及如何与氢和一氧化碳反应形成简单的碳氢化合物和较高分子量的含氧物质。 使用钌催化剂。众所周知，该系统可产生多种化合物； 这项工作应提供控制条件所需的知识，以最大限度地提高所需物种的产量。
