Catalytic Organic Solid Wastes Valorization Using Natural Gas

随着人口的增加，废物流的压力继续增加，导致环境风险和处理成本增加。然而，70%以上的有机固体废物，如农林废物，含有有用的热值，可以加以利用。天然气是化石燃料中最清洁的能源，是加拿大广泛存在的一种丰富的自然资源。由于其化学惰性和相对较低的体积能量密度，天然气目前主要用于住宅取暖和烹饪，很少用于运输或化工生产。该项目旨在开发一种创新的集成催化工艺，能够以经济和环境友好的方式有效地同时将有机固体废物和天然气转化为高附加值的液体燃料和/或化学品，并在中试规模上成功示范，生物质干处理能力不低于1吨/d，液体产品产生率不低于0.3吨/d。拟议项目的成果将有助于优化加拿大碳氢资源的利用，同时减少随之而来的环境影响。丰富的有机固体废物资源，加上对液体运输燃料的需求，是拟议设计项目的关键动机。拟议的技术有可能影响加拿大能源行业的运营，进而可能在帮助创建一个不依赖传统来源和转换方法的能源系统方面产生社会影响。这一领域的进展将使加拿大在开发低成本碳资源定价技术方面走在前列，鉴于加拿大传统和非传统资源的规模，这一点尤其重要，并有助于加拿大在提供具有积极经济和环境影响的创新能源解决方案方面保持领先地位。

As population increases, the pressures on waste streams continue to grow, resulting in increased environmental risk and processing costs. Yet more than 70% of organic solid wastes such as agricultural and forestry wastes contain useful heating value which could be utilized. Natural gas, the cleanest energy source among fossil fuels, is an abundant natural resource widely present in Canada. Due to its chemical inertness and relatively low volumetric energy density, natural gas is currently dominantly used for residential heating and cooking with little use for transportation or chemical production applications.The proposed project aims to develop an innovative integrated catalytic process which can effectively simulteneously convert organic solid wastes and natural gas to high value-added liquid fuels and/or chemicals in an economically profitable and environmentally friendly way and get it successfully demonstrated at a pilot scale with biowastes processing capacity of no less than 1 ton/d on a dry basis and liquid product generation rate of no less than 0.3 ton/d.The outcome from the proposed project will benefit optimizing the utilization of Canada's hydrocarbon resources, while reducing the accompanying environmental impact. The abundance of organic solid waste resources, coupled with the demand for liquid transportation fuel, are key motivators for the proposed design project. The proposed technologies have the potential to impact the operations of the Canadian energy industry and, in turn, could have a social impact in helping to create an energy system not dependent upon traditional sources and conversion methods. Advances in this field should put Canada at the forefront in the development of low-cost carbon resources valorization technologies, which is especially important given the size of the conventional and unconventional resources in Canada, and help Canada maintaining leadership in providing innovative energy solutions with positive economic and environmental impacts.
