✦ Synopsis
This volume consists of a collection of 24 contributed papers from engineers and scientists working in the processing of petroleum and distillates.The authors, from many different parts of the world, presented their work at the American Institute of Chemical Engineers National Meeting, held in Houston from 28 March to 1 April 1993.
The era of processing light oils in refineries is almost over. There is a strong push for processing heavy oils, bitumen and "bottom-of-the-barrel". Processing heavy oil poses several problems, related with obtaining state-of-the-art technologies at reasonable capital and operating costs. In addition, there are problems associated with the selection of the best catalyst which can tolerate a high content of organic impurities (S.N.O.) and metals (V, Ni and Fe) in the "bottom-of-barrels". Recent regulations on the content of aromatics and sulphur in diesel fuels as well as environmental concern on SO× and NOx emissions from mobile and stationary combustion facilities have made it imperative to think of new ways and means to meet new, more stringent product specifications. To address the above considerations, this book provides a comprehensive review of the scientific and technological issues associated with catalytic hydroprocessing of petroleum and distillates. The papers presented at the symposium can be broadly classified in terms of content into the following four categories:
(1) Catalyst deactivation, (2) Upgrading of heavy oils and residue, (3) Hyclrotreating of distillates, (4) General papers.
Catalyst deactivation: A review on activation in hydrotreating of residue by C.H. Bartholomew focuses on the deactivation of sulphided Mo, CoMo and NiMo catalysts in hydrotreating heavy residue feedstocks. Coke formation, metal deposition and the deactivation rate as a function of feedstock and catalyst properties are discussed. M.C. Oballa discusses catalyst deactivation in residue hydrocracking. The choice of the best catalyst for hydrocracking heavy oil or residue as well as deactivation rate have been dealt with in this paper.
Upgrading of heavy oils and residue: A chapter written by G. Nonobri deals with the frontiers of using newly developed H-oil catalyst for hydrocracking residual feedstocks at high conversion. Upgrading desulphated shale oil over mechanical mixtures of sulphided cobaltmolybdenum and nickel-molybdenum alumina supported catalysts are the subject of the paper by P. Geneste et al. The role of Ni and Co promoters on the individual behaviour of sulphided catalysts on the residual cracking activity are examined. V.K. Mathur discusses the rapid hydrolysis of atmospheric and vacuum resid oil. The results showed a high percentage of total conversion and also conversion to low boiling products without the use of high pressure and catalyst. S.S. Shih elucidates the combination of hydrovisbreaking and hydrotreating, which upgrades the overall residue conversion and also reduces residue viscosity without excess sediments. This approach is found to be attractive for the production of low sulphur heavy fuels. The major advantages of mild hydrocracking of heavy oil with modified alumina based catalyst has been dealt with by EB. Dai et al. K. Kretschmar reviews the technical, economic and environmental aspects of residuum upgrading by high-pressure
