摘要

氢(H2)被认为是获得清洁能源的替代品中有前途的能量载体,因为它具有高能量效率(122千焦/克),并且可以通过生物过程从木质纤维素废物中获得。在瓜纳华托州,种植番茄产生了大量的植物废料,因为这种作物主要是通过保护农业生产的。因此,本研究的目的是考虑番茄植物残留物通过厌氧消化过程产氢。两种来源的接种物,番茄植物的原生菌群和厌氧污泥在100°C预处理24 h;在初始pH为6.5±0.2的条件下,对四种矿物介质进行了批量实验。在原生菌群和含酵母浸膏的矿物培养基中,产量最高可达37.4 mLH2 / g SV。产氢的发现与文献中报道的其他类型的废物一样,突出了不需要预处理底物或接种物。因此,所提出的方法对番茄植株残体制氢是有效的。

Producción de Hidrógeno mediante digestión anaerobia de residuos de planta de jitomate
Hydrogen (H2) is recognized as a promising energy carrier among the alternatives for obtaining clean energy, since it has a high energy efficiency (122 kJ / g) and can be obtained from lignocellulosic waste through a biological process. In the state of Guanajuato, high amounts of plant waste derived from tomato cultivation are generated because this is the crop mostly produced through protected agriculture. So, the objective of the present study was to consider tomato plant residues for the generation of hydrogen through the anaerobic digestion process. Two sources of inoculum, native microflora of the tomato plant and anaerobic sludge pretreated at 100 ° C for 24 h; and four mineral media at an initial pH of 6.5 ± 0.2 in batch experiments, were evaluated. The highest yield was 37.4 mLH2 / g SV using native microflora and mineral media with yeast extract. Hydrogen production was found like those reported in the literature for other type of waste, highlighting the no-need to pretreat the substrate or inoculum. Therefore, the methodology propose is efficient to the hydrogen production from tomato plant residues.
