Resid conversion hydroconversion

Another hydrogenation process utilizes internally generated hydrogen for hydroconversion in a single-stage, noncatalytic, fluidized-bed reactor (41). Biomass is converted in the reactor, which is operated at about 2.1 kPa, 800°C, and residence times of a few minutes with steam-oxygen injection. About 95% carbon conversion is anticipated to produce a medium heat value (MHV) gas which is subjected to the shift reaction, scmbbing, and methanation to form SNG. The cold gas thermal efficiencies are estimated to be about 60%.

Hydroconversion (variously referred to as hydrotreating and hydrocracking) is a group of refining processes in which the feedstock is heated with hydrogen under pressure. The outcome is the conversion of resids to a range of products. 

Experiments were run using 0.9%, 2.0%, 3.0%, and 5.0% sulfided molybdenum naph-thenate (as the percent of molybdenum in the resid) to select a catalyst level. Standard conditions of 30 min at 420°C at a 3 1 tetralin/resid ratio, 3 wt % sulfided molybdenum naphthenate catalyst, and 1500 psi of hydrogen pressure were selected for determination of the relative reactivity to hydroconversion of the coal-derived vacuum resids. It was found that both catalyst concentration and hydrogen pressure have strong effect on the conversion of coal to hydrocarbon.
