FEASIBILITY OF USING A TUBE REACTOR IN HIGH-INTENSITY FISCHER-TROPSCH SYNTHESIS

摘要

This article considers some of the problems associated with the use of a tube reactor in high-intensity Fischer-Tropsch (FT) synthesis with heavy loads of processed syngas (3000-5000 h~(-1) ). The main factor preventing the development of highly efficient FT synthesis is removal of the heat released. Intensification of the heat-exchange process may be possible by accelerating the convective heat-exchange component by increasing the linear speed of the gas flow from 0.1 to 10 m/sec. Required values of the heat-exchange coefficient, and the fictitious linear velocities of the gas flow at which maximum degree of CO processing is attained without disruption of the stable operating temperature regime of the reactor have been calculated. The expediency of reactive-gas circulation in FT synthesis is demonstrated.
