This project will develop technology for potentially monetizing millions of tons of carbon rich solid waste like low rank-coal lignite and petroleum coke (Petcoke) that are abundantly available in Canada. These hydrocarbons are most commonly used for generating heat and power, both of which are combustion applications generating significant amounts of greenhouse gas emissions (GHG). Additionally, because of the high carbon and impurities (nitrogen, sulphur etc.) content in these feedstocks, their end-use GHG impact is more severe compared with using other fossil fuels such as natural gas. In this project, we are introducing a technology called oxy-cracking, a combination of two reactions taking place simultaneously in a water-based medium, for converting these feedstocks into useful chemicals for non-combustion application. Additionally, the CO2 emissions in the proposed process are negligible compared with the incumbent technology for producing these chemicals from lignite and other waste carbonaceous feedstocks. This technology is a cost-effective technique as it takes place at low pressures and temperatures and favors the production of humic acid analogs that find application as bulk fertilizers. The proposed research will optimize and scale up this technology at a lab scale. The long term goal is to develop a process capable of reliably producing high yields for humic acids from low rank-coals, while recycling back the water used in the process. This generates a product from a solid waste and reduces the pollutants in the air emissions. Efficient oxy-cracking process has the potential to i) provide humic acids for subsequent sale; ii) position Canada well to lead the global marketplace for humic acids production from low rank-coals. HQPs will gain experience in process design and advanced chemical reaction techniques that are also applicable to residual feedstocks of oil and gas industry.

该项目将开发技术，潜在地将加拿大大量可获得的数百万吨富碳固体废物，如低阶煤、褐煤和石油焦(石油焦)货币化。这些碳氢化合物最常用于产生热量和电力，这两者都是产生大量温室气体排放(GHG)的燃烧应用。此外，由于高碳和杂质(氮、硫等)。与使用天然气等其他化石燃料相比，这些原料的最终用途对温室气体的影响更为严重。在这个项目中，我们引入了一种名为氧裂化的技术，这是一种在水基介质中同时发生的两种反应的组合，用于将这些原料转化为非燃烧应用的有用化学品。此外，与现有的从褐煤和其他废碳质原料生产这些化学品的技术相比，拟议工艺中的二氧化碳排放量微不足道。这项技术是一项具有成本效益的技术，因为它是在低压和温度下进行的，有利于腐植酸类似物的生产，这些类似物可用作散装肥料。这项拟议的研究将在实验室规模上优化和扩大这项技术。长期目标是开发一种能够可靠地从低变质煤中生产高腐植酸的工艺，同时回收工艺中使用的水。这将从固体废物中产生一种产品，并减少空气中的污染物排放。高效的氧化裂解工艺有可能：1)为后续销售提供腐植酸；2)使加拿大在从低变质煤生产腐植酸的全球市场上处于领先地位。HQP将在工艺设计和先进的化学反应技术方面获得经验，这些技术也适用于石油和天然气工业的残渣原料。
