New catalyst development for upgrading of crude oil is proposed, to address critical issues pertinent to the commercial use of heavy bitumen and the stringent regulatory limitations on environmentally damaging sulfur and nitrogen content. Deep desulfurization/denitrogenation of high sulfur/nitrogen bitumen, necessary for the competitive production of refined fuels and petrochemicals, is capital-intensive and unsustainably energy-intensive with current catalyst technology. Low pressure bitumen hydrotreating can address such problems, but little more than incremental improvements can be anticipated from traditional bulk metal sulfide catalysts. The problems associated with low pressure catalytic denitrogenation is particularly relevant to upgrading the bitumen produced from Alberta's oilsands resource.

提出了用于升级原油的新催化剂开发，以解决与重型沥青的商业使用以及对环境破坏硫和氮含量的严格监管限制有关的关键问题。高硫/氮沥青的深度硫化/否定性，对于精制燃料和石化的竞争性生产所必需的是资本密集型且具有目前的催化技术的能源密集型。低压沥青水力处理可以解决此类问题，但是从传统的散装金属硫化物催化剂中可以预期的是增量的改进。与低压催化否硝化作用相关的问题与升级艾伯塔省油砂资源产生的沥青特别相关。
