摘要生物质甲烷生产系统有潜力提供全国天然气年需求量的25%。与这种转化过程相关的生产系统是厌氧消化设施。间歇式生物质消化器系统的最佳操作需要在固定时间范围内调度来自多个原料的所有批次。这些系统的一个显著特征是原料在蒸煮器系统中使用之前在储存中腐烂。消化器中的最佳批次停留时间必须考虑生产率以及储存的生物质的衰减率。为了在规划期内实现最大沼气产量，必须考虑可用时间、生物量、沼气生产率和储存衰减率。本文讨论了单一和多个原料在一个单一的消化系统的调度。采用动态规划算法求解了单原料分批调度时间问题。
Abstract Biomass to methane production systems have the potential of supplying 25% of the yearly national natural gas demand. The production systems associated with this conversion process are anaerobic digestion facilities. The optimal operation of a batch biomass digester system requires the scheduling of all batches from multiple feedstocks during a fixed time horizon. A significant characteristic of these systems is that the feedstock decays in storage before use in the digester system. The optimal batch residence times in the digester must account for the production rate as well as the decay rate of stored biomass. The availability times, biomass quantities, biogas production rates and storage decay rates must all be taken into account for maximal biogas production to be achieved during the planning horizon. This paper addresses the scheduling of both single and multiple feedstocks in a single digester system. The single feedstock batch scheduling time problem is solved by a dynamic programming algor...
