CO2 enhanced bio-oil extraction from renewable microalgae for enzymatic production of biodiesel: a process for converting CO2 into fuel

找到乙醇生产的副产品CO2的有益用途，以生产增值产品，具有巨大的潜力来抵消CO2去除的成本，使商业案例可以基于经济效益而不仅仅是环境法规，这将使Spectrum具有高度的竞争力。微藻，CO2爱好植物，将CO2转化为油，然后可以转化为生物柴油。使用可再生微藻代替化石燃料作为碳氢化合物燃料的来源提供了一种负CO2排放途径。拟议项目的目标是开发一种酶法工艺，将从烟道气流中捕获的CO2转化为液态烃燃料。具体而言，一步低成本，活性，选择性和稳定的酶促过程将被开发，以加速CO2增强的生物油提取从可再生微藻和随后的生物柴油燃料的转化。将可再生生物能源与碳捕获和利用相结合将导致大气CO2的净负减少。如果这一过程被证明是可行的，由二氧化碳产生的燃料可能会成为一种主要的能源。此外，拟议项目的成功将为Spectrum提供一个具有成本效益的选择，以抵消温室气体排放，并帮助萨斯喀彻温省和加拿大在能源生产和环境管理方面成为世界领先者。

Finding a beneficial use for CO2, by product of ethanol production, to produce value-added products has agreat potential to offset the cost of CO2 removal to a level where a business case can be made based oneconomic benefits rather than environmental regulations alone which will make Spectrum highly competitive.Microalgae, CO2 loving plants, converts CO2 into oil that can then be converted into biodiesel. Usingrenewable microalgae instead of fossil fuels as a source of hydrocarbon fuels provides a negative CO2emissions route. The objective of the proposed project is to develop an enzymatic process for converting theCO2 captured from flue gas streams into liquid hydrocarbon fuel. Specifically, a single step low cost, active,selective and stable enzymatic process will be developed to accelerate CO2 enhanced bio-oil extraction fromrenewable microalgae and subsequent conversion to biodiesel fuel. Combining renewable bioenergy withcarbon capture and utilization would result in a net-negative reduction of atmospheric CO2. If the processproves feasible, fuel created from CO2 may become a major source of energy. Also, success in the proposedproject will produce a cost-effective option for Spectrum to offset greenhouse gas emissions and helpSaskatchewan and Canada to grow as a world leader in both energy production and environmental stewardship.
