Fundamental studies of catalytic processing of synthetic liquids
This project revolves around understanding the fundamental processes involved in the catalytic removal of harmful oxygenated organics present in coal liquids. The investigators are modelling the complex type of sulfided Mo catalyst proposed for these reactions with simple single crystal surfaces. They then investigate the reaction pathways for representative simple oxygenates upon these surfaces. The original plans for this quarter called for continuing study of the interesting reactions of furan on sulfided Mo(100) surfaces presented in the last report. Due to the unfortunate accidental destruction of this sample, the investigators have in fact proceeded on two alternate fronts. First they have improved the sample heating system, the malfunction of which caused the loss of the Mo crystal. Secondly, they have prepared a Mo(110) surface and performed initial experiments to understand the sulfur phases that form on this surface of Mo. These efforts have been worthwhile - they have accomplished on the (110) surface in two months what required almost six months on the (100) surface, and are in a good position to repeat the furan reaction experiments on Mo(110) surfaces. The heating system design is described and results of surface properties are given. 2 refs., 5 figs.
