厌氧消化的最终产物是甲烷和二氧化碳，已被用于从废弃生物质中生产沼气，作为替代能源。为了实现基于微生物过程的创新现代技术，需要将厌氧消化的氢气（水解和产酸）和甲烷生成（产丙酮和产甲烷）阶段分开，以分别有利于在受控条件下产生氢气和甲烷。之前，我们开发了一个基准（3升和3.5升生物反应器）两阶段厌氧消化系统，在中温条件下，从甜菜精炼工业的富含蔗糖的副产品中产生氢气（阶段1）和甲烷（阶段2）作为主要的能源底物。最近，用于氢气和甲烷生产的两级系统已经成功地扩大了10倍（中试规模），目前在波兰的一家糖厂运行。氢气和甲烷的生产效率与装置规模成正比。获得的结果导致了进一步研究的发展目标，最终结果将是糖厂作为气体生物燃料生产商的创新解决方案。
Anaerobic digestion, whose final products are methane and carbon dioxide, has been used to produce biogas from waste biomass as an alternative energy source. For the purpose of innovative, modern technologies based on microbial processes, it is desirable to separate the hydrogen-(hydrolysis and acidogenesis) and methane-yielding (acetogenesis and methanogenesis) stages of anaerobic digestion to respectively favor the production of hydrogen and methane under controlled conditions. Previously, we developed a benchscale (3- and 3.5-litre bioreactors) two-stage anaerobic digestion system producing hydrogen (in stage 1) and methane (in stage 2) from sucrose-rich by-products of the sugar beet refining industry as the primary energy substrates under mesophilic conditions. Recently, the two-stage system for hydrogen and methane production has been successfully scaled up 10-fold (a pilot scale) and currently operates in one of the Polish sugar factories. The efficiency of hydrogen and methane production were directly proportional to the scale of installation. The obtained results led to the development objectives of further research that the end result will be an innovative solution for the sugar factory as a producer of gaseous biofuels.
