Avoiding Temperature Runaway in Hydroprocessing Reactors
Temperature excursion or temperature runaway is the abnormal process condition at which catalyst bed temperatures go high beyond the normal operating limit on account of uncontrolled hydrocracking reactions. During a...

Reducing Coke Formation on Hydrotreating Catalysts
Coke formation is the deposition of hydrogen deficient carbonaceous material over the catalyst surface. Generally, it is formed by thermal condensation, de-hydrogenation, and polymerization reactions of hydrocarbons. The coke covers...

Hydrotreating Process in Oil Refinery
Hydrotreating, Hydroprocessing, or Hydrodesulfurization is a process in which the petroleum feed stream reacts with Hydrogen at high temperature and pressure in the presence of a catalyst, to remove the...

Grading or Guard bed Catalysts in Hydrotreating Reactors
Grading and guard bed catalysts are the macro-porous, grading material at the inlet of the hydrotreating reactor to remove fouling agents and save the main reactive hydrotreating catalyst from fouling...
