A new reactor that counteracts catalyst deactivation by coke

Posted by Miguel from Universidad de ZaragozaResponsive · Knowhow and Research output · Spain

Summary of the technology

A two-zone fluidized bed reactor can solve the problems of catalyst deactivation by coke by providing in-situ continous catalyst regeneration.

Description of the technology

By feeding a carbon containing compound at an intermediate point of a fluidized bed and a regenerating gas (e.g. containing O2, CO2 or H2O) at the bottom, two zones with different reaction atmosphere are created. In the top zone the desired reaction is produced and in the bottom zone the catalyst is regenerated. Examples of application include: hydrogen production by reforming of methane, ethanol or glycerol; methane aromatization; propane dehydrogenation.

The system can be complemented by adding a membrane for hydrogen removal.
