In this work, a biorefinery system including castor bean seeds and microalgae is used as a case study to evaluate the integration of second and third generation biorefineries. A biorefinery concept was applied for the combined production of polyol, ethylene-glycol, omega-3 acid, biodiesel, methanol and heat and power from castor bean and microalgae. Castor bean cake and microalgae paste were used to feed a biomass-fired system (BIGCC), where part of CO2 produced in flue gas is captured and employed as substrate for microalgae growth. To evaluate the performance of this biorefinery concept three scenarios based on different levels of mass and energy integration were modeled and assessed from techno-economic and environmental points of view. The scenario with the best economic and environmental performances was the one including full mass integration, full heat integration, and cogeneration scheme.
在这项工作中，以一个包括蓖麻籽和微藻的生物精炼系统作为案例研究，来评估第二代和第三代生物精炼厂的整合情况。应用了一种生物精炼概念，用于从蓖麻籽和微藻联合生产多元醇、乙二醇、ω-3酸、生物柴油、甲醇以及热和电力。蓖麻籽饼和微藻糊被用于为生物质燃烧系统（BIGCC）供料，在该系统中，烟气中产生的部分二氧化碳被捕获并用作微藻生长的底物。为了评估这种生物精炼概念的性能，从技术经济和环境角度对基于不同质量和能量整合水平的三种情景进行了建模和评估。经济和环境性能最佳的情景是包括完全质量整合、完全热整合和热电联产方案的情景。
