(652g) Modifications of Fischer-Tropsch Product Distribution in Modular Reactor Systems

            A
synthetic fuels program using energy resources more abundant than petroleum
presents a potential solution to the impending crude oil shortage.  The Fischer-Tropsch (FT) synthesis has
the capability of producing such fuels by converting coal or biomass derived
synthesis gas into hydrocarbons. 
As currently performed in industry, the reaction generates a wide
spectrum of hydrocarbons that require further refining to attain the desired
products.

            The
research described here aims to narrow the selectivity of the Fischer-Tropsch
synthesis to products in the gasoline and diesel ranges, namely C₈
to C₁₆ hydrocarbons. 
The approach to accomplish this is based on novel reaction engineering
schemes and modifications in catalyst composition.  The experimental design for this research employs two or
more plug flow reactors in series. 
Reaction variables that are used in an attempt to shift the
Fischer-Tropsch product distributions include temperature, and downstream
co-fed species, and catalyst type. Concepts such as electrochemical catalyst
promotion and atom transfer radical polymerization will be discussed.
