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，以使数百万吨富含碳的固体废物（如低排名的褐煤和石油焦炭（Petcoke））在加拿大可用的技术中获利。这些碳氢化合物最常用于产生热量和功率，这两种都是燃烧应用，产生了大量的温室气体排放（GHG）。此外，由于这些原料中的碳和杂质（氮，硫等）的含量很高，因此与使用其他化石燃料（如天然气）相比，它们的最终使用GHG影响更为严重。 在这个项目中，我们引入了一项称为氧裂缝的技术，这是在水基培养基中同时进行的两种反应的组合，用于将这些原料转换为有用的化学物质，以进行非燃烧应用。此外，与现有的技术相比，拟议过程中的二氧化碳排放量可以忽略不计，该技术用于从褐煤和其他废碳原料中生产这些化学物质。这项技术是一种具有成本效益的技术，因为它发生在低压和温度下，并有利于腐殖酸类似物的产生，这些腐殖酸类似物发现施用是散装肥料。 拟议的研究将以实验室规模优化和扩展这项技术。 长期目标是开发一个能够可靠地产生低级别少量腐殖酸产量的过程，同时回收该过程中使用的水。 这是从固体废物中产生的产品，并减少了空气排放中的污染物。有效的氧化过程具有i）为后续销售提供腐殖酸的潜力； ii）加拿大的位置很好地领导全球从低排名群体产生腐殖酸的市场。 HQP将获得工艺设计和高级化学反应技术的经验，这些技术也适用于石油和天然气行业的残留原料。
