Supply options future hydrogen

For this study, the committee was not able to examine all of the options that may shape the future competition. Figure 2-9 illustrates the comparisons that were developed within this study. In particular, the committee focused on the competition between vehicles with on-board storage fuel cell vehicles supplied by molecular hydrogen in competition with internal combustion, gasoline-fueled vehicles, either as conventional vehicles or as gasoline hybrid electric vehicles. 

Hydroisomerization is one of the few major refinery processes that allow refineries to cope with the future fuel regulations on the one side and the necessity to supply premium fuel with the necessary octane on the other side. Due to the limited volume the chemical industry can cope with in addition to the present level, future reduction of the aromatics in fuels will force the refineries to convert as much of the aromatics as possible to fuel components. One possible option is to feed the one-ring aromatics such as benzene to an isomerization unit. A state of the art hydroisomerization catalyst such as HYSOPAR is very active for benzene hydrogenation at temperatures as low as 100°C, where 100% hydrogenation is achieved, and can cope with up to 15 wt.-% of benzene in the feed. When sulfur in the range of 50 ppm is present in the feed, a partial inhibition of...
