Effect of Hydrotreatment on Product Sludge Stability

摘要

During severe hydrotreating, several chemical changes take place in the oil, which may lead to the formation of unstable products in which asphaltenic precipitates are released either in the downstream equipment or during storage or products. In the ongoing development of new hydrotreating processes and catalysts it is important to take steps to minimize this tendency. Hence, the chemistry and stability o two oils of Middle East origin have been followed as a Function of reactor temperature.
