“…The anaerobic digestion (AD) process of algal biomass of low lipid content produces a significantly larger amount of energy compared with biodiesel alone (Bohutskyi et al 2014b). The conversion rate of biomass depends greatly on the species of algae and the digestion and pretreatment method (Dębowski et al 2013). In a non-defined mixed culture of freshwater algae, the methane concentration of biogas varies between 40 and 65 % (De Schamphelaire and Verstraete 2009).…”

Effect of co-substrate feeding on methane yield of anaerobic digestion of Chlorella vulgaris

et al. 2016

Microalgal production has many advantages over the use of terrestrial plants; therefore, increases in the use of microalgae for energy production can be expected. Algal biomass can be processed anaerobically to methane; however, the unfavorable C/N ratio of the substrate may have an inhibitory effect. The impact of the application of used cooking oil, maize silage, and mill residue on anaerobic co-digestion of the microalgal Chlorella vulgaris was studied in semi-continuous, laboratory-scale digestion. During the full period of the trial involving anaerobic digestion of algae in the case of mono-digestion and co-digestion with used cooking oil, maize silage, and mill residue, the volumetric methane yields were 0.38 ± 0.07, 1.56 ± 0.26, 1.19 ± 0.18, and 1.16 ± 0.13 L L −1 , respectively. Trials were carried out to determine the long-term effect of the total solid (TS) content of substrates (co-digestion of C. vulgaris and used cooking oil at 3.8 and 7.2 % of TS, respectively). Both designs could be increased to 5.5 g VS L, but a higher TS% resulted in increased methane production and a longer period of decline in the methane yield due to washout. The sharp decrease in methane content at the end of 90 days was accompanied by a reorganization of the methanogenic archaeal community.

“…The algal biomass productivity is estimated at 100-150 t/ ha, which is 10-15 times higher than the conventional agricultural crops (Chinnasamy et al 2010). As energy feedstock, it can be transformed into many types of biofuels: biodiesel, biohydrogen, biogas or it may also be used for direct combustion (Pienkos and Darzins 2009;Dębowski et al 2013). Literature data indicate that conversion of the algae biomass into biogas is a highly profitable solution and the obtained methane achieves 140-360 mL/g volatile solids (VS) depending on the algal species (Wang and Park 2015).…”

“…Moreover, the date of harvest and the parts of plant used as a biogas substrate also determine the biomass characteristics (Peng et al 2011). In turn, the C/N ratio of algae biomass is generally below 10, which may cause a high concentration of ammonia nitrogen and volatile fatty acids in anaerobic reactors, leading to an inhibition of methanogenesis (Zhong et al 2012;Dębowski et al 2013). …”

Anaerobic Co-digestion of the Energy Crop Sida hermaphrodita and Microalgae Biomass for Enhanced Biogas Production

et al. 2017

This study presents the results of anaerobic codigestion of perennial crop Sida hermaphrodita and microalgae biomass under semi-continuous conditions. The aim of this study was to compare biogas potential from the silage of Sida mixed in different ratios with microalgal species of Chlorella sp. and Scenedesmus sp. The results showed that the co-digestion process improved biogas/ methane production to the level of 594.52/351.88 mL/g volatile solids. The best results were achieved when microalgae biomass constituted 40 and 60% of the substrate, and C/N ratio ranged from 14.69 to 20.61. The composition of digestates was also determined.

“…Moreover, because these higher alcohols have good solvent capabilities, they can easily be blended with diesel and biodiesel [12,13]. The alternative fuels are derived from animal fats or in the cultivation process of algae [14,15]. In practice the combustion process of more than one fuel is possible by using dual fuel technology or blend mode.…”

Co-combustion of biodiesel with oxygenated fuels in direct injection diesel engine

2017

Abstract. The paper presents results of experimental investigation of cocombustion process of biodiesel (B100) blended with oxygenated fuels with 20% in volume. As the alternative fuels ware used hydrated ethanol, methanol, 1-butanol and 2-propanol. It was investigated the influence of used blends on operating parameters of the test engine and exhaust emission (NOx, CO, THC, CO2). It is observed that used blends are characterized by different impact on engine output power and its efficiency. Using biodiesel/alcohol blend it is possible to improve engine efficiency with small drop in indicated mean effective pressure (IMEP). Due to combustion characteristic of biodiesel/alcohol obtained a slightly larger specific NOx emission. It was also observed some differences in combustion phases due to various values of latent heat of evaporation of used alcohols and various oxygen contents. Test results confirmed that the combustion process occurring in the diesel engine powered by blend takes place in a shorter time than in the typical diesel engine.
