摘　　要：介绍了加拿大油砂资源情况、主要性质、改质技术现状和原油外输能力,重点调研了有工业应用潜力的部分改质技术,包括工艺技术现状、核心流程、技术特点和存在问题等。从部分改质产品性质、改质深度、改质过程的碳排放强度、是否存在副产品等多种维度,分析油砂沥青部分改质技术的未来发展趋势。其中对油砂沥青进行缓和热裂解,或缓和热裂解结合沥青质脱除技术是油砂沥青部分改质的技术核心;目标是在满足加拿大管道要求的前提下,尽可能减少稀释剂用量、保证部分改质产品的稳定性,降低改质工艺过程的碳排放强度。The resource condition,main properties,current status of upgrading technology and crude oil export capacity of oil sands in Canada were introduced,and focusing on the investigation of some partial upgrading technologies with potential industrial application,including process technology status,core process,technical characteristics and existing issues.The future development trend of oil sand bitumen partial upgrading was analyzed from multiple dimensions,such as the properties of partial upgraded products,severity of upgrading,carbon emission intensity of upgrading process and issues of by-products.Among them,moderating thermal cracking of oil sand bitumen,or moderating thermal cracking combined with asphaltene removal technology were the technical core of oil sand bitumen partial upgrading.The goal was to reduce the amount of diluent as much as possible,maintain the stability of some upgraded products,and reduce the carbon emission intensity of the upgrading process on the premise of meeting the specification of pipeline in Canada.
