Abstract

Research to date has mainly focused on the properties and efficiency of the production of selected, individual types of biofuels from microalgae biomass. There are not enough studies investigating the efficiency of the production of all energy sources synthesised by these microorganisms in a single technological cycle. The aim of this research was to determine the possibilities and efficiency of the production of hydrogen, bio-oil, and methane in the continuous cycle of processing T. subcordiformis microalgae biomass. This study showed it was feasible to produce these three energy carriers, but the production protocol adopted was not necessarily valuable from the energy gain standpoint. The production of bio-oil was found to be the least viable process, as bio-oil energy value was only 1.3 kWh/MgTS. The most valuable single process for microalgae biomass conversion turned out to be methane fermentation. The highest specific gross energy gain was found after applying a protocol combining biomass production, hydrogen biosynthesis, and subsequent methane production from T. subcordiformis biomass, which yielded a total value of 1891.4 kWh/MgTS. The direct methane fermentation of T. subcordiformis biomass enabled energy production at 1769.8 kWh/MgTS.

绿色微藻 Tetraselmis subscordiformis 培养过程中多种生物燃料的生产分析

迄今为止的研究主要集中在利用微藻生物质生产特定种类生物燃料的特性和效率方面。对这些微生物在单一技术循环中合成的所有能源的生产效率进行调查的研究还不够多。这项研究的目的是确定在处理亚堇菜微藻生物质的连续循环中生产氢气、生物油和甲烷的可能性和效率。研究结果表明，生产这三种能源载体是可行的，但从能源增益的角度来看，所采用的生产方案并不一定有价值。研究发现，生物油的生产是最不可行的工艺，因为生物油的能值仅为 1.3 千瓦时/兆瓦时。微藻生物质转化中最有价值的单一工艺是甲烷发酵。亚堇菜生物质的生物质生产、氢气生物合成和随后的甲烷生产相结合的方案可产生 1891.4 kWh/MgTS 的总价值，从而获得最高的特定总能量收益。亚绳木霉生物质直接进行甲烷发酵产生的能量为 1769.8 kWh/MgTS。
