“…The sulfide NiMo catalyst acted as a bifunctional catalyst for hydrogenation of squalene to squalane followed by cracking of the formed squalane to shorter-chain hydrocarbons. Zhao et al explored the hydrotreating of extracted algal lipids from Nannochloropsis for the production of aviation fuel [129]. The effect of hydrotreating temperature (270-350 • C) and catalyst loading (10-30%) was investigated.…”

The depletion of fossil fuel has drawn growing attention towards the utilization of renewable biomass for sustainable energy production. Technologies for the production of algae derived biofuel has attracted wide attention in recent years. Direct thermochemical conversion of algae obtained biocrude oil with poor fuel quality due to the complex composition of algae. Thus, catalysts are required in such process to remove the heteroatoms such as oxygen, nitrogen, and sulfur. This article reviews the recent advances in catalytic systems for the direct catalytic conversion of algae, as well as catalytic upgrading of algae-derived oil or biocrude into liquid fuels with high quality. Heterogeneous catalysts with high activity in deoxygenation and denitrogenation are preferable for the conversion of algae oil to high-grade liquid fuel. The paper summarized the influence of reaction parameters and reaction routes for the catalytic conversion process of algae from critical literature. The development of new catalysts, conversion conditions, and efficiency indicators (yields and selectivity) from different literature are presented and compared. The future prospect and challenges in general utilization of algae are also proposed.

In the aviation sector, the use of biofuels has increased worldwide, therefore, this study assesses the environmental impact of these mass-based blends, named BK0, BK10, BK20 and BK30, according to their composition (Biodiesel + Kerosene) and the percentage of mass fraction. The study uses life cycle analysis with the SimaPro software and the Ecoinvent database for Colombia. The stages of cultivation, oil extraction and refining were established for biodiesel, while for the kerosene the stages defined were crude oil extraction and its refining. Results show that the stage with the greatest impact is the cultivation and extraction for both the category of freshwater ecotoxicity, acidification and terrestrial eutrophication.keywords: Biodiesel, Freshwater Ecotoxicity, Acidification, Terrestrial Eutrophication, Life Cycle. RESUMEN.En el sector de la aviación, el uso de biocombustibles se ha incrementado a nivel mundial, por lo tanto, se evaluará el impacto ambiental de estas mezclas con base másica, llamadas BK0, BK10, BK20 y BK30 de acuerdo con su composición (Biodiesel + queroseno) y con el porcentaje de fracción másica presente. El estudio utiliza análisis de ciclo de vida con el software SimaPro y la base de datos Ecoinvent para Colombia. Se establecieron para el biodiesel las etapas de cultivo, extracción de aceite y refinación, para el queroseno se definieron las etapas de extracción del crudo y su refinación. Se evidencia que la etapa que mayor presenta impacto es el cultivo y la extracción tanto para la categoría de ecotoxicidad de agua dulce, acidificación y eutrofización terrestre.Palabras clave: biodiesel, ecotoxicidad de agua dulce, acidificación, eutrofización terrestre, ciclo de vida.

“…Meanwhile, energy reuses of the waste biomass have been explored, which include anaerobic digestion to biogas or extracting the lipid (Tyagi and Lo 2013;Bora et al 2020;Luo et al 2020). Microalgae are known to have relatively higher lipid content, and also they have the advantage of high growth rate, as well as a high ability to fix carbon dioxide (Shi et al 2018). The lipid in microalgae was reported to be converted into jet fuel, indicating the big potential for industry use (Ju et al 2018).…”

A new algal-bacterial granular sludge treatment method was used to treat salty eutrophication water. The results indicated that the treatment removed more than 98% of the total inorganic nitrogen and the total phosphorus after a 15 d cultivation period using 2% salinity simulated eutrophication water. For the 4% salinity simulated water, the total phosphorus was not able to be removed and was even higher in the effluent; and the total inorganic nitrogen was only removed 17%. Thus, the algal-bacterial granules were efficient for removing nitrogen and phosphorus in 2% salinity eutrophication water but were not effective for 4% salinity water. High levels of filamentous algae proliferation growing on the surface of the granules was primarily responsible for the good performance in 2% salinity water. However, the lipid accumulation was greatly enhanced (reactor R2 at a 27.6% increase and reactor R4 at a 107% increase) for both granule types due to the algal growth. Thus, treatment of the salty eutrophication water can also greatly increase the added-value of the algal-bacterial granules.
