A flow diagram for a proposed shale oil refinery is shown in Figure 5. An FCC unit is used as the primary cracking process. This refinery produces high-octane gasoline and diesel fuel. Jet fuel also could be produced by severely hydrogenating a kerosene cut (10) from the whole-oil hydrotreater or by using a hydrocracker in place of the FCC. The... [Pg.45]

Although SRC-II was basically a thermal liquefaction process, it was most successful using bituminous coals with a high native pyrite content. Iron sulfides are well known to have catalytic properties for coal liquefaction. Recycling part of the ash-minerals-containing bottoms had two beneficial effects (1) it increased the pyrite concentration in the reactor feed, and (2) it increased the residence time for heavy components, thus giving them more time to hydrocrack to distillate products. A block flow diagram of the SRC-II process is shown in Fig. 19.19. [Pg.890]

Three licensors, Foster Wheeler USA Corp, Kellogg Brown Root, Inc., and UOP LLC, offer flow diagrams and a discussion of their process in Hydrocarbon ProcessingP These process vendors cumulatively report over 110 commercial applications of this technology. Each licensor offers their process for application in lube processing or in the preparation of catalytic cracker or hydrocracker feed. All vendors also discuss the use of supercritical conditions for solvent recovery. This is discussed later under Solvent Recovery. ... [Pg.2794]

A typical flow diagram for hydrocracking is shown in Fig. 15.17. Process flow is similar to hydrotreating in that feed is pumped to operating pressure, mixed with a hydrogen-... [Pg.504]
