Many oil refineries employ hydroprocessing for removing sulfur and other impurities from petroleum feedstocks. Capable of handling heavier feedstocks than other refining techniques, hydroprocessing enables refineries to produce higher quality products from unconventional — and formerly wasted — sources. Hydroprocessing of Heavy Oils and Residua illustrates how to obtain maximum yields of high-value products from heavy oils and residue using hydroprocessing technologies.
While most resources on hydroprocessing concentrate ongas oil and lower boiling products, this book details the chemistry involved and the process modifications required for the hydroprocessing of heavy crude oils and residua. Emphasizing the use of effective catalysts to ensure cleaner and more efficient industrial fuel processes, the book presents key principles of heterogeneous catalyst preparation, catalyst loading, and reactor systems. It explains how to evaluate and account for catalysts, reactor type, process variables, feedstock type, and feedstock composition in the design of hydroprocessing operations. The text concludes with examples of commercial processes and discusses methods of hydrogen production.
To meet the growing demand for transportation fuels and fuel oil, modern oil refineries must find ways to produce high quality fuel products from increasingly heavy feedstocks. Hydroprocessing of Heavy Oils and Residua contains the fundamental concepts, technologies, and process modifications refineries need to adapt current hydroprocessing technologies for processing heavier feedstocks.

However, with respect to the prevailing context of fuel industries, hydrogenation
did not seem to be economical for application to petroleum fractions. At least two
factors dampened interest: (1) the high cost of hydrogen and (2) the adequacy of
In addition, products of volatility intermediate between that of the overhead
fractions and bottoms (residua) are withdrawn as sidestream products.
Furthermore, steam is injected into the base of the column and the sidestream
strippers to adjust ...
The fractions obtained by vacuum distillation of reduced crude oil depend on
whether the run is designed to produce lubricating or vacuum gas oils. In the
former case, the fractions include: 1. Heavy gas oil, an overhead product used as
These advantages may be of little consequence when it is not, for various
reasons, the intention to recover the various product fractions in toto or in the
original state, but in terms of the compositional evaluation of different feedstocks
