Lecture within the activities of scientific and cultural activity

Within the scientific and cultural activities for the first semester of the Department of Chemical Engineering for the academic year 2019-2020, a master’s student, a lecture was given by Kholoud Salem Dawood entitled:

Preparation of composite-modified Iraq clays for the hydro desulfurization of heavy fuels

And that was in the presence of the Head of the Chemical Engineering Department, Assist. Prof. Dr. Jamal Manea Al-Rubaie, Distinguished Greeters, Branch Heads, and a number of teaching staff, employers, and master’s students in Al-Khwarizmi Hall on Thursday, January ninth, 2020.

The oil refining industry has considerably grown during the 20th century to become an important part of everyday modern activity. One of the main objectives of heavy fuels processing is to reduce their very high sulfur ratio. This project aims to prepare and characterize different types of catalysts using kaolin Iraq's clay (metakaolin materials with big pores from natural clays of Iraq).

Metakaolin was introduced into alumina as a composite support for hydrodesulfurization process and use series of the active metal (e.g. nickel, iron, cobalt, silver, copper and molybdenum). The catalyst was prepared by the incipient wetness impregnation (IWI) method and characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), FT-IR, pore volume and BET surface area. Their hydrodesulfurization (HDS) activity for heavy fuels (gas oil) were evaluated and compared in different parameters (temperature, pressure etc.) by a fixed bed reactor while kinetics of the HDS reaction was studied using the different catalysts separately. Apply this process through a mathematical model.
