评估了四种原料在需求驱动的沼气系统中的使用情况。对青贮饲料、食物垃圾、指状海带和奶牛浆料进行了生物甲烷潜力 (BMP) 测定。对所有原料进行了半连续试验，评估沼气和生物甲烷的生产。比较了半连续试验的三种动力学模型。与脉冲馈送半连续系统中的气体产量最准确相关的一阶模型。该模型是为按需生产电力和生物甲烷升级而开发的。该模型检验了理论上的青贮饲料消化器，该消化器在连续饲喂系统中可产生 435 kWe。适应需求驱动的沼气需要 187 分钟才能产生足够的甲烷来运行 2 MWe 热电联产 (CHP) 装置 60 分钟。升级系统在 CHP 关闭后 71 分钟进行调度。产生的沼气中 21% 用于热电联产，79% 用于升级系统。
Four feedstocks were assessed for use in a demand driven biogas system. Biomethane potential (BMP) assays were conducted for grass silage, food waste,Laminaria digitataand dairy cow slurry. Semi-continuous trials were undertaken for all feedstocks, assessing biogas and biomethane production. Three kinetic models of the semi-continuous trials were compared. A first order model most accurately correlated with gas production in the pulse fed semi-continuous system. This model was developed for production of electricity on demand, and biomethane upgrading. The model examined a theoretical grass silage digester that would produce 435 kWein a continuous fed system. Adaptation to demand driven biogas required 187 min to produce sufficient methane to run a 2 MWecombined heat and power (CHP) unit for 60 min. The upgrading system was dispatched 71 min following CHP shutdown. Of the biogas produced 21% was used in the CHP and 79% was used in the upgrading system.
