“…Cultivation of microalgae attracts increasing attention as a source of lipid for biodiesel (41). Using of microalgae as a source of lipids has many advantages (42,43), such as (1) simple cultivation, (2) high rate of biomass growth with high lipid content, (3) no need to alienate fertile soil, and (4) no dependence on the cost of food resources. A complete life cycle of microalgae ends within a few days and the cells reproduce themselves using sunlight as a source of energy and carbon dioxide as a source of carbon (44).…”

Although fossil fuels remain the main source of energy, the volume of renewable sources of energy is constantly increasing. Biodiesel is a promising alternative fuel due to the number of advantages compared to fossil fuel and other types of biofuel. The specific objective of this study was to identify the difference between conventional and novel technologies applied during the whole life cycle of biodiesel production and consumption. The study offers some important insights into the recent advances in the biodiesel industry including biodiesel production from microalgal lipids, advanced homogenous and enzymatic transesterification, non-catalytic supercritical transesterification, application of microwave and ultrasound assisting technologies. Considering all the factors affecting the efficiency and safety of the biodiesel production process, here we reviewed the main principals and recent achievements in the environmental life cycle assessment of biodiesel production and consumption.

“…In recent years, biomass has attracted much attention mainly because it can be used as a renewable resource to produce various high-quality chemicals, multi-functional char-based materials, and fuel products, which can not only reduce the burden of relying on fossil resources, but also are regarded as a meaningful way toward CO 2 emissions [1][2][3][4][5][6]. Currently, biomass energy accounts for about 9% of the world's total energy supply that plays a key role in tacking issues of energy-supply security and environmental problems [7].…”

“…Among them, pyrolysis is recognized as an advanced and In this work, ex situ catalytic pyrolysis of biomass over char-supported Ni and/or Fe catalysts for syngas production and tar decomposition was investigated. The objectives of this this study were to (1) synthesize char-based catalysts by impregnation with metal (Fe and/or Ni), (2) compare the catalytic activity of char-based catalysts for syngas production and tar decomposition, and (3) discuss the catalytic mechanism of biomass over char-based catalyst.…”

Ex situ catalytic pyrolysis of biomass using char-supported nanoparticles metals (Fe and Ni) catalyst for syngas production and tar decomposition was investigated. The characterizations of fresh Fe-Ni/char catalysts were determined by TGA, SEM–EDS, Brunauer–Emmett–Teller (BET), and XPS. The results indicated that nanoparticles metal substances (Fe and Ni) successfully impregnated into the char support and increased the thermal stability of Fe-Ni/char. Fe-Ni/char catalyst exhibited relatively superior catalytic performance, where the syngas yield and the molar ratio of H2/CO were 0.91 Nm3/kg biomass and 1.64, respectively. Moreover, the lowest tar yield (43.21 g/kg biomass) and the highest tar catalytic conversion efficiency (84.97 wt.%) were also obtained under the condition of Ni/char. Ultimate analysis and GC–MS were employed to analyze the characterization of tar, and the results indicated that the percentage of aromatic hydrocarbons appreciably increased with the significantly decrease in oxygenated compounds and nitrogenous compounds, especially in Fe-Ni/char catalyst, when compared with no catalyst pyrolysis. After catalytic pyrolysis, XPS was employed to investigate the surface valence states of the characteristic elements in the catalysts. The results indicated that the metallic oxides (MexOy) were reduced to metallic Me0 as active sites for tar catalytic pyrolysis. The main reactions pathway involved during ex situ catalytic pyrolysis of biomass based on char-supported catalyst was proposed. These findings indicate that char has the potential to be used as an efficient and low-cost catalyst toward biomass pyrolysis for syngas production and tar decomposition.

The idea of using microalgae as a biosource of biodiesel is being taken seriously because of the escalating price of fossil fuel. The objective the research was to determine the optimal levels of concentrations of sulfate, carbonate, nitrate and phosphate in the performance of biomass, by assessing the individual and combined effect of concentrations on the growing of the microalgae, through the application of a type-24 factorial experimental design in the performance of Botryococcus braunii biomass isolated in the high-Andean zone of Cajamarca-Perú. According to the results of the study of individual effects of these four salts, it was stated that carbonate and nitrate salts have significant effect on the growing of Botryococcus braunii (p<0.05). This was characterized by using a chromatography equipment of gases adapted to mass and it was found that hydrocarbons generated have 26 to 32 carbons in their composition.
