China-US Team Develops New Platinum-Cobalt Nanocatalysts for Low-Temperature Aqueous Phase Fischer—Tropsch Synthesis...

摘要

Researchers from China and the U.S. have developed Pt-Co nanoparticles (NPs) which proved to be effective and efficient catalysts for aqueous-phase Fischer-Tropsch synthesis (FTS) at 433 K (160 °C)—a lower operational temperature than can be achieved with conventional catalysts. FTS is a well-established catalytic process that converts syngas derived from fossil fuels or biomass to liquid fuel products. As the process is highly exothermic and thermodynamically favored at low temperature, it is desirable to develop a catalyst system that could facilitate working at low reaction temperature while maintaining excellent catalytic performance, they note. Research has shown that Ru, Fe and Co catalysts working in the temperature range of 200-350 °C have the best performance. Among these, less expensive Co-based catalysts are the optimal choice for industrial synthesis of long-chain hydrocarbons due to their higher hydrocarbon productivity, good stability, and commercial availability.
