【 摘 要 】

This study examines how existing U.S. refining infrastructure matches in geography and processing capability with the needs projected from anticipated biofuels production. Key findings include:  a potential shortfall in both overall hydrotreating capacity and hydrogen production capacity in refineries to manage the conversion of certain bio-derived feedstocks having high oxygen contents;  a regional concentration of anticipated biofuel resources, placing added stress in particular refining regions (e.g. the Gulf Coast);  uncertainties surrounding the impact of bio-derived fuel intermediates on the refiner’s ability to meet product performance and product quantity demands, and the need for better and more comprehensive chemical composition information;  the need for considerably more data and experience on the behavior of projected biofuels feedstocks in refining processes (e.g. impacts on process performance and reliability);  and the need to examine the optimum capital investment locations for additional processing equipment. For example, whether it is better to further refine biofuels at the new production sites, in centralized biofuel "depots", or whether the existing refining facilities should be expanded to better handle a more 'raw' biofuel.
