Shaped catalyst sections for gas cracking furnace - of bulbous external form with central passage, threaded on central gas outlet tube

摘要

Shaped catalyst sections lie within an outer reactor tube and are carried on a central metal tube which also forms the gas outlet passage. They are used in catalytic gas cracking reactors heated by furnace gases or by hot gases from a nuclear reactor. Ready removal of spent catalyst with minimum downtime is possible. Low and constant press. drop in service is obtd.
