Novel catalysts for hydrodesulfurization and hydrodenitrogenation of heavy bitumen under mild conditions

建议开发新的原油改质催化剂，以解决与重沥青商业使用相关的关键问题，以及对环境有害的硫和氮含量的严格监管限制。高硫/氮沥青深度脱硫脱氮是生产精制燃料和石化产品所必需的，在目前的催化剂技术下是资本密集型和不可持续的能源密集型。低压沥青加氢处理可以解决这些问题，但传统的块状金属硫化物催化剂只能带来渐进的改进。与低压催化脱氮相关的问题与艾伯塔省油砂资源生产的沥青升级特别相关。

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.
