ABSTRACT
Hydrotreating (variously referred to as hydroprocessing to avoid any confusion with those processes that are referred to as hydrotreating processes) is a refining process in which the feedstock is treated with hydrogen at temperature and under pressure (Gary and Handwerk, 1984; Bridge, 1997). The outcome is the conversion of a variety of feedstocks to a range of products (Table 16-1; Figure 16-1).
