Summary
The principal objectives of this project are to discover and evaluate. novel heterogeneous catalysts for conversion of syngas to oxygenates having use as fuel enhancers, to explore novel reactor and process concepts applicable in this process, and to develop the best total process for converting syngas to liquid fuels. The project is being pursued as two concurrent tasks. Task 1 involves catalyst research and development and is being largely conducted by catalyst chemists and analytical specialists. Task 2 is largely an engineering activity, and includes process conceptualization and economics and bench-scale process evaluation of systems developed in Task 1. Work this quarter has concentrated largely on literature work, revamping laboratory and reactor systems, and planning specific experiments to pursue the objectives of the program. A systematic search of the literature has been initiated to ensure that our literature base on conversion of syngas to higher alcohols is current. This activity will be continued throughout the project. Variables in catalyst formulation and preparation will be examined by a fractional factorial designed experiment. The variables are based upon previous work at UCC on a catalyst system that gave a product rich in isobutanol. The ranges of some of the fixed and free variables are being identified by a preliminary 3 × 3 designed set. The precipitation pH and its effects on surface area, porosity, and thermal characteristics of the resulting precipitate will also be investigated. Potentiometric titrations during coprecipitation are being used to aid in improving this catalyst preparation procedure. A microreactor system has been prepared for use in screening heterogeneous catalysts in this project. It will allow the independent control of three fixed bed reactor tubes except for reaction temperature. Appropriate temperature, pressure, and flow ranges are attainable with this system.
