ABSTRACT:

An exploratory, experimental process study was conducted on the direct conversion of coal derived synthesis gas to gasoline. Novel, proprietary catalysts, supplied by Mobil Research and Development Corporation were used. These unique catalysts do not yield oxygenates and the hydrocarbons formed are limited in size to about C sub 11 . Consequently, both gasoline selectivity and quality exceeds that of the gasoline produced in the Fischer--Tropsch process. This new technology was compared with conventional Fischer--Tropsch. The experiments were conducted in micro reactor (10 cc catalyst capacity) and in bench-scale units (150 cc catalyst capacity). The bench-scale unit was used in both a fixed and fluid bed mode. The studies included effects of temperature, pressure and space velocity on catalyst performance, and catalyst activation, aging and regeneration. Theoretical studies were made to support the process research. Mobil Research and Development Corporation has discovered a series of catalysts that will convert coal-derived synthesis gas to high octane number gasoline in selectivities higher than predicted by the Schultz--Flory equation. The process potential of these catalysts was assessed under Contract No. EX-76-C-01-2276, jointly funded by DOE and Mobil Research and Development Corp. (ERA citation 04:048045)
