This work discloses how the pretreatment of wheat straw with acetic acid (AA) solutions modifies biomass composition, strongly affecting pyrolysis product distribution. AA in diluted is a renewable and eco-friendly reagent, being also one main components bio-oil* (water-free basis). In comparison water ammonia treatments, washing leads to higher removal degree alkali alkaline-earth elements (AAEMs) from ash. addition, reduces content char gas precursors, as case soluble lignin extractives. Consequently, yield drastically increased up ∼53 wt% during washed straw, much than value obtained for raw (∼35 wt%). Likewise, composition highly improved by AA, dramatically increasing concentration levoglucosan, which valuable precursor produce both advanced biofuels bio-based chemicals. contrast, opposite occurs extracted matter samples, recovered solutions, since its high AAEMs, extractives promotes formation gases detriment bio-oil fraction. Based on preliminary techno-economic analysis, it concluded that may improve significantly economic performance process. due incomes coming levoglucosan largely compensate additional capital fresh costs.

Because of its low environmental impact and high production, microalgae bio-oil has quickly become a popular renewable fuel option. The process utilizes which are readily available in nature to produce an alternative fossil fuel. Although microalgal production mechanisms have been previously reviewed recent studies, comparatively few them emphasize the significance algal through all conversion from microalgae. Here we review common processes microalgae, upgrading, commercial aspects utilization. most efficient route can be identified by analysing both biomass feedstock final product. For example, pyrolysis high-energy bio-oil, but it also produces large amounts char gas. hydrothermal liquefaction gasification more complex costly, they potential with greater consistency. However, expense using context is major concern. cost producing typically higher than that conventional fuels. Several factors, including cost, availability, necessary infrastructure, contribute uncertainty bio-oil's feasibility. With constant improvements technology government support, however, emerge as viable
