“…Fast pyrolysis: a fast heating rate at short duration and high temperature to produce bio-oil [2], which can be used directly as fuels, petroleum replacement or employed as a valuable source of chemicals [91,92]. The temperature is around 400°C during high contact time with a yield of 35% that is rich in phytol, fast pyrolysis of algae biomass is easier than other lignocellulosic biomass because of the absence of phenolic compounds [92]. Bio-oil is perceived as the mid-way between energy and chemical products, suitable for further refining process in downstream operations [90].…”

“…The high protein content of most algae species was emphasized by Yang, et al [64] as the reason for high nitrogen and oxygen content in bio-oil produced from pyrolysis which resulted in low heating value, low pressure, and low thermal stability. This high protein concentration and lipids could give a liquid that can be considered as a great addition to valuable compounds [92]. The heating value of bio-oil produced from this conversion process is lower than petroleum diesel and higher heating than other lignocellulosic feedstock, which defines its suitability for fuel oil use [67].…”

An algal feedstock or biomass may contain a very high oil fraction, and thus could be used for the production of advanced biofuels via different conversion processes. Its major advantage apart from its large oil fraction is the ability to convert almost all the energy from the feedstock into different varieties of useful products. In the research to displace fossil fuels, algae feedstock has emerged as a suitable candidate not only because of its renewable and sustainable features but also for its economic credibility based on the potential to match up with the global demand for transportation fuels. Cultivating this feedstock is very easy and could be developed with little or even no supervision, with the aid of wastewater not suitable for human consumption while absorbing CO2 from the atmosphere. The overall potential for algae applications generally shows that this feedstock is still an untapped resource, and it could be of huge commercial benefits to the global economy at large because algae exist in millions compared to terrestrial plants. Algae applications are evident for everyday consumption via foods products, non-foods products, fuel, and energy. Biofuels derived from algae have no impact on the environment and the food supply unlike biofuels produced from crops. However, any cultivation method employed could control the operating cost and the technicalities involved, which will also influence the production rate and strain. The scope of this paper is to review the current status of algae as a potential feedstock with diverse benefit for the resolution of the global energy demand, and environmental pollution control of GHG.

“…While liquid phase (biofuel) which usually consist of several type of compounds including aromatics, phenols and nitrogenated compound was formed from condensed volatile tar as the product of devolatilization and primary tar cracking. The solid residue (bio char) left by thermochemical process consist of unreacted carbon and several minerals, depend on what type of biomass was used (Hong et al, 2017).…”

Microalgae is known as the future bioenergy resources due to its unlimited potential and availability. One of the numerous paths to acquire an energy source is gasification, which produce syngas and methane as a hydrocarbon fuel or feedstock product. To set up an efficient gasification plant, several essential information is needed including the effect of oxidizing agent and steam to carbon (S/C) ratio to energy efficiency on certain biomass properties. This paper aims to study the highest exergy possibility on microalgae gasification process by examining the effect of steam and air flowrate independently via ASPEN Plus simulation. The result was validated with experimental data to verify the simulation reliability. It was found that the thermodynamic based simulation is suitable to predict the reactor behavior and acquire an optimum operating condition.Keywords: microalgae; gasification; exergy; simulation

“…Macroalgae, known as well as seaweed, consist of multicellular organisms composed of high quantities of carbohydrates. This property, besides the little or no lignin content, make them interesting for bioethanol or biobutanol production (Dave et al, 2019;Hong et al, 2017;Jin et al, 2013;Kostas et al, 2016). Moreover, their size goes from a few millimeters to many tens of meters (Ganesh Saratale et al, 2018).…”

Concerns about fossil fuels depletion has led to seek for new sources of energy. The use of marine biomass (seaweed) to produce biofuels presents widely recognized advantages over terrestrial biomasses such as higher production ratio, higher photosynthetic efficiency or carbon-neutral emissions. In here, interesting seaweed sources as a whole or as a residue from seaweed processing industries for biofuel production were identified and their diverse composition and availability compiled. In addition, the pretreatments used for seaweed fractionation were thoroughly revised as this step is pivotal in a seaweed biorefinery for integral biomass valorization and for enabling biomass-to-biofuel economic feasibility processes. Traditional and emerging technologies were revised, with particular emphasis on green technologies, relating pretreatment not only with the type of biomass but also with the final target product(s) and yields. Current hurdles of marine biomass-to-biofuel processes were pinpointed and discussed and future perspectives on the development of these processes given.
