Traditionally hydrotreating processes can be used to decrease the viscosity of heavy crude oil, improve the API gravity, and reduce the sulfur content of the oil. Using hydrogen in heavy oil upgrading is well known and can enhance the properties of the oil, but the costs of hydrotreating are relatively high due to the consumption of high pressure H2 (>8 MPa). An alternative approach to obtain the benefits of hydrogen addition is to add a cheap and abundant H-donor to the heavy crude oil, such as methane, the main component of natural gas. The goal of the current project is to develop a cost-effective partial upgrading technology to enhance the quality of heavy conventional for not only satisfying the pipeline transportation specification, but also producing high-value added petrochemicals. This will be done using a technology based on the directly catalytic incorporation of natural gas (i.e. methane - methanotreating) into the heavy oil at mild temperatures and pressures (no higher than 5 MPa) compared to hydrotreating (i.e. 400 oC and 16 MPa H2) as natural gas prices are far more economically advantageous compared to H2, leading to enhanced productivity and reduced production cost and thus improved profitability. Furthermore, the incorporation of natural gas into the transportable oil product will minimize greenhouse gas emission from upgrading process, making it more environmentally friendly. Moreover, the outcomes obtained from the proposed research will create a novel way of methane activation and liquefaction, leading to the breakthrough in the field of catalysis and its application in clean energy conversion. Moreover, the achievement made from this project will further ascertain the leading position of Canada in the world's energy market through more efficient and cleaner utilization of heavy crude oil and natural gas which are abundant natural resources in Canada.

传统的加氢处理工艺可用于降低重质原油的粘度，提高API比重，并降低油的硫含量。在重油改质中使用氢气是众所周知的，并且可以提高油的性质，但是由于高压H2（>8 MPa）的消耗，加氢处理的成本相对较高。获得氢加成益处的替代方法是向重质原油中添加廉价且丰富的H-供体，例如天然气的主要组分甲烷。本项目的目标是开发一种具有成本效益的部分升级技术，以提高重常规的质量，不仅满足管道运输规范，而且还生产高附加值的石化产品。这将使用基于天然气直接催化结合的技术来完成在温和的温度和压力下，与加氢处理相比，（即400 oC和16 MPa H2），因为与H2相比，天然气价格在经济上更有利，从而提高了生产率并降低了生产成本，从而提高了收益率。此外，在可运输的石油产品中加入天然气将减少升级过程中的温室气体排放，使其更加环保。此外，从拟议的研究中获得的结果将创造一种新的甲烷活化和液化方式，导致催化领域的突破及其在清洁能源转化中的应用。此外，该项目的成果将通过更有效和更清洁地利用加拿大丰富的重质原油和天然气资源，进一步确定加拿大在世界能源市场上的领先地位。
