Data obtained from seven lab‐scale experiments were used to compare different methods for describing effects of substrate disintegration on methane yield. Statistical evaluation underlines the importance of careful design and precise conduction of experiments. Within continuous experiments conducted as duplicates, an effect 5.65 times (triplicates: 3.07 times) the standard deviation between identically operated digesters can be considered significant. Some tests show significant impacts; however, the results between different test approaches, namely, batch, continuous digestion (measured), and continuous digestion (modeled from batch tests), are inconsistent. This inconsistency hints at a limited transferability from batch results to continuous operation in general and for the effect of disintegration in particular.

评估基质分解对甲烷收率的影响

从七个实验室规模的实验中获得的数据用于比较描述底物分解对甲烷产率影响的不同方法。统计评估强调了精心设计和精确进行实验的重要性。在重复进行的连续实验中，相同操作的蒸煮器之间的标准偏差的5.65倍（三次：3.07倍）的影响可以认为是显着的。一些测试显示了显着的影响。但是，不同测试方法之间的结果不一致，即分批，连续消解（测量）和连续消解（根据分批测试建模）。这种不一致提示通常从批处理结果到连续操作的转移能力有限，尤其是崩解的影响。
