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二氧化碳的有益用途来生产附加值产品，具有极大的潜力来抵消二氧化碳去除成本，达到可以基于经济效益而不是仅基于环境法规的商业理由的水平，这将使Spectrum具有很强的竞争力。微藻是一种喜欢二氧化碳的植物，它将二氧化碳转化为石油，然后再转化为生物柴油。使用可再生微藻而不是化石燃料作为碳氢燃料的来源提供了一条负二氧化碳排放途径。拟议项目的目标是开发一种酶法工艺，将从烟气中捕获的二氧化碳转化为液态碳氢化合物燃料。具体地说，将开发一种低成本、活性、选择性和稳定的一步酶法工艺，以加速从可再生微藻中提取二氧化碳强化生物油并随后转化为生物柴油。将可再生生物能源与碳捕获和利用相结合，将导致大气中二氧化碳的净负减少。如果这一过程被证明是可行的，从二氧化碳中产生的燃料可能成为主要的能源来源。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发展成为能源生产和环境管理方面的世界领先者。

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.
