This Small Business Innovation Research Phase I project will demonstrate a more effective and economical process for extracting the chemical and energy resources from lignocellulosic biomass. Existing lignocellulosic pretreatment technologies use any of a variety of chemicals, heat, and mechanical energy to separate the poorly hydrolyzed lignin from the cellulose, and hemicellulose for enzymatic hydrolysis to sugars, and fermentation of sugars to alcohol, or in the case of anaerobic digestion to biogas. The use of chemicals, or operation at high temperatures and pressures dictate the cost of pretreatment. This research will investigate a process that pretreats lignocellulosic biomass at low temperature and pressure without the use of chemicals. The process operates with very low energy inputs and may be driven by waste heat. The broader impact/commercial potential of this project will be the adoption of an economical process for the efficient extraction of energy and chemical resources from biomass. The pretreatment process will be used for the production of liquid and gaseous fuels from lignocellulosic biomass. The process will be used to reduce waste residuals from biomass processing by increasing the percentage of the biomass converted to renewable energy. Potential markets include agricultural enterprises that produce liquid and gas fuels from energy crops or crop residues, such as bio-refineries, farms with anaerobic digesters, composting facilities, municipal and industrial solid waste facilities, confined animal feeding operations (CAFOs) and bio-refineries for pre and post consumer solid waste processing. The process is expected to lower the cost of bioenergy production and thereby improve its use while reducing GHG emissions.

该小企业创新研究第一阶段项目将展示一种更有效、更经济的从木质纤维素生物质中提取化学和能源的工艺。现有的木质纤维素预处理技术使用多种化学品、热量和机械能中的任何一种来将难水解的木质素与纤维素和半纤维素分离，以酶促水解成糖，并将糖发酵成酒精，或者在厌氧消化的情况下发酵成沼气。 化学品的使用或在高温高压下的操作决定了预处理的成本。这项研究将研究一种在低温低压下不使用化学品预处理木质纤维素生物质的工艺。该过程的运行能量输入非常低，并且可能由废热驱动。该项目更广泛的影响/商业潜力将是采用一种经济的工艺，从生物质中高效提取能源和化学资源。预处理工艺将用于从木质纤维素生物质生产液体和气体燃料。该工艺将通过增加生物质转化为可再生能源的百分比来减少生物质加工中的废物残留。潜在市场包括利用能源作物或作物残渣生产液体和气体燃料的农业企业，例如生物精炼厂、配有厌氧消化池的农场、堆肥设施、市政和工业固体废物设施、封闭式动物饲养场（CAFO）以及用于消费前和消费后固体废物处理的生物精炼厂。该工艺预计将降低生物能源的生产成本，从而改善其利用，同时减少温室气体排放。
