Influence of feedstock composition on the pressure drop buildup in gas oil hydrotreater

Chimica Techno Acta
In this work two samples of solid particulates obtained from the intergranular space of the guard beds catalyst of industrial gas oil hydrotreating reactors were investigated. The hydrotreating reactors were operated on feedstock of different composition.
