Hydrodenitrogenation of Heavy Oil (Part 4)

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...

[Heavy silicone oil (Densiron® 68) in proliferative vitreoretinopathy: 4 years of experience].

METHOD Prospective observational study including 10 patients (age range: 27-74 years) with recurrent retinal detachment (RD) and proliferative vitreoretinopathy (PVR) and 2.8 mean unsatisfactory previous surgeries. Densiron® was injected in all patients, with surgical retinectomy being required in 70% of them. Minimum follow-up time was 12 months. RESULTS The mean length of time before Densir...

1 2 Can rapeseed oil replace olive oil as part of a Mediterranean - style diet ? 3 4

26 This narrative review compares evidence from experimental, epidemiological and 27 clinical studies of the health benefits of rapeseed (Canola) oil and olive oil in order to 28 assess if rapeseed oil is suitable as a sustainable alternative to olive oil as part of a 29 Mediterranean-style diet in countries where olive trees do not grow. From 30 epidemiological studies, the evidence for cardio...
