Hydrodenitrogenation of Heavy Oil (Part 1)

Heavy Metal Pollution from Dental Clinics–Part 1:Annual Emissions Assessment

This study aimed to evaluate the concentration of heavy metals in liquid effluents and to quantify the mercury content in dental amalgam waste generated by dental clinics. Three neighbouring cities in Northeast Algeria were considered in this study (Constantine, Skikda, and Annaba). Heavy metals, such as Hg, Cu, Zn, Fe, Ni, Mn, Cr, Cd, and Pb, were analysed in wastewater and then compared with ...

Development of Heavy Oil Hydrocracking Catalysts

This paper present some results obtained from the research program being pursued at the Research Institute of King Fahd University of Petroleum and Minerals aimed at the development of suitable catalysts for hydrocracking of the vacuum gas oils from Arabian Light crude to obtain higher quality distillate products. The newly developed high-performance hydroprocessing catalysts are based on synth...

Bioremediation of Heavy Crude Oil Contamination

Crude oil contamination is one of the major environmental concerns and it has drawn interest from researchers and industries. Heavy oils contain 24-64% saturates and aromatics, 14-39% resins and 11-45% asphaltene. Resins and asphaltenes mainly consist of naphthenic aromatic hydrocarbons with alicyclic chains which are the hardest to degrade. Crude oil biodegradation process, with its minimal en...
