Cassava (Manihot esculenta) is a woody bush extensively cultivated as an annual crop in tropical and subtropical regions for its edible starchy tuberous root, a major source of carbohydrates. The main residue from its cultivation is the cassava stalk, which is normally used as soil fertilizer or in culture propagation. The main goal of this paper is to evaluate two routes (biochemical and thermochemical) for bioenergy production (ethanol and synthesis gas—electricity) using cassava stalk as raw material. A detailed techno-economic and energy assessment is carried out based on the simulation approach of both conversion routes to determine the production costs of main products and the overall energy efficiency of the processes. The electricity production costs vary from 0.008 to 0.037 USD/MJ, whereas the ethanol production costs range from 1.11 to 2.02 USD/L (including subsidies). The change in the production costs was observed due to the assumptions of the model, e.g., cassava stalk, transportation, and enzyme costs. The overall energy efficiency of the gasification and ethanol fermentation was 68.7 and 25.1%, respectively.

木薯秸秆作为乙醇和电力生产原料的经济和能源价值评估

木薯(Manihot esculenta)是一种木本灌木丛,由于其可食用的淀粉状块根(碳水化合物的主要来源)而广泛种植于热带和亚热带地区的一年生作物中。木薯秸秆的主要残留物是木薯秸秆,通常用作土壤肥料或用于养殖繁殖。本文的主要目的是评估以木薯秸秆为原料的生物能源生产的两种途径(生化和热化学)(乙醇和合成气-电力)。基于两种转化途径的模拟方法,进行了详细的技术经济和能源评估,以确定主要产品的生产成本和流程的整体能源效率。电力生产成本从0.008到0.037 USD / MJ,而乙醇生产成本从1.11到2。02美元/升(含补贴)。由于模型的假设(例如木薯茎,运输和酶的成本),观察到了生产成本的变化。气化和乙醇发酵的总能量效率分别为68.7%和25.1%。
