RECONSTRUCTION OF RADIAL CATALYST CONCENTRATION DISTRIBUTION IN AN EXPERIMENTAL TYPE FCC RISER<br />

Journal Title: Metrology and Measurement Systems - Year 2007, Vol 14, Issue 1

Abstract

A gamma ray tomographic reconstruction of catalyst concentration distribution in laboratory experiments is presented. The images are generated by gamma transition measurements in an experimental riser simulating flow experiments. The manual scanner is adequate for mapping radial catalyst concentration distribution under spatial resolution of 0.002 m and density resolution of 10 kg/m3.
