Biomass utilization, a component of international effort on greenhouse gas (GHG) mitigation, is in its very early stages. Biomass facilities are a mix of demonstration and "real" projects, and are typically on smaller scale, using truck transportation to deliver the feedstock. Depending on the distance traveled, transport costs could be as high as 50% of the cost of raw material. It is becoming evident that the economies of scale require the future biorefineries to be of a size approaching petrochemical facilities; the drive for larger scale has emerged strongly in the last few years, including critical work in Europe and the United States. Large biorefineries could require as much as 20,000 tonnes of biomass per day; transporting and processing bulk volumes of biomass using pipeline is becoming an attractive option to reduce cost and road congestion. Slurry pipeline transport is a well established technology in the oil sands, but it has not been applied to biomass. Simultaneous transportation and processing of biomass in the pipeline would reduce the cost of production of bioproducts/ethanol from lignocellulosic biomass. Critical parameters that would enable the design and economic analysis of this concept of use of pipeline for transportation and processing of biomass have not been measured. The overall goal of this research is aimed at enabling large scale utilization of pipeline for transportation and processing of biomass in the form of a slurry of chopped agricultural biomass and water. The key projects of this program, are to experimentally measure the impact of adding enzymes to the biomass pipeline on the critical design parameters, including extent of breakdown of biomass in the pipeline during transportation, rheological properties as a function of slurry concentration, settling properties (including critical velocities), maximum concentrations, pressure drops, pumping characteristics of adding of enzymes in a biomass slurry in a laboratory scale set-up. Results will be used to develop models for scale-up to commercial size. The requested research grant will support a research group to carry out this work.

生物量利用率是国际温室气体（GHG）缓解措施的组成部分，正处于早期阶段。生物质设施是示范和“真实”项目的混合，通常使用卡车运输来提供原料。根据行进的距离，运输成本可能高达原材料成本的50％。规模经济要求未来的生物精炼厂的大小接近石油化学设施。在过去的几年中，大规模发展的动力已经大大出现，包括在欧洲和美国的重要工作。大型生物工业每天可能需要多达20,000吨的生物量；使用管道运输和处理大量生物质的大量生物质已成为降低成本和道路拥堵的有吸引力的选择。浆液管道运输是油砂中一项良好的技术，但尚未应用于生物质。管道中生物量的同时运输和加工将降低木质纤维素生物量的生物产生/乙醇的生产成本。尚未衡量将管道用于运输和处理生物质的概念的设计和经济分析的关键参数。这项研究的总体目标旨在以大规模利用管道来运输和以切碎的农业生物质和水的泥浆形式运输和加工生物质。 The key projects of this program, are to experimentally measure the impact of adding enzymes to the biomass pipeline on the critical design parameters, including extent of breakdown of biomass in the pipeline during transportation, rheological properties as a function of slurry concentration, settling properties (including critical velocities), maximum concentrations, pressure drops, pumping characteristics of adding of enzymes in a biomass slurry in a laboratory scale set-up.结果将用于开发用于扩大商业规模的模型。要求的研究赠款将支持研究小组进行这项工作。
