直接脂質抽出を使用することによる廃水スラッジからのバイオディーゼル生産のための脂質回収効率の向上

 

Usman Muhammad、GEDES(MEXT Scholarship)D1

石油燃料の需要と使用の増加は、地下の化石燃料のレベルと環境にも有害です。廃棄物(バイオマス)の管理と利用によって化石燃料に取って代わるバイオ燃料生産への関心が高まっています。バイオディーゼルは、同じ可能性を秘めたさまざまな食用および非食用資源から生産される有望なバイオ燃料の1つです。  石油ディーゼルとして。その原料と前処理のために、それは高いという大きな挑戦を持っています 1リットルあたり4.4ドルから6.0ドルの範囲の製造コスト。下水汚泥は、  高世代で無料で入手できるため、バイオディーゼル生産の潜在的な供給源ですが それでも、乾燥プロセスが50%を超えるという、生産コストという同じ課題があります。私たちの新しいアプローチは、乾燥を排除した直接脂質抽出によってバイオディーゼルを生産することです さまざまな抽出段階を使用することによるプロセスと効率的な脂質回収。

The increasing demands and use of petroleum fuels are harmful to the underground fossil fuels level and environment as well. There is a growing interest in biofuel production to replace fossil fuels by managing and utilization of wastes (biomass). Biodiesel is one of the promising biofuels produces from different edible and non-edible resources which has the same potential as petroleum diesel. Due to its feedstock and pre-treatment, it has a great challenge of high production cost which ranges from $4.4 to $6.0 per liter. Sewage sludge has been tested as a potential source of biodiesel production because of high generation and free availability but still, it has the same challenge of production cost in which the drying process contributes >50%. Our new approach is to produce biodiesel by direct lipids extraction with the elimination of the drying process and efficient lipids recovery by using different extraction stages.

Glycerol upgrading via thermo-electrocatalytic deoxygenation

Glycerol is a by-product of biodiesel manufacturing, saponification process, fatty acid and bioethanol industries. Thus, the value of glycerol is decreasing in the global market due to its surplus. Electrochemical valorization of biomass-derived feedstocks, glycerol, into biofuels offers a sustainable method for utilization of biomass waste and for greener biofuel manufacturing under milder operating conditions. Here, we investigate the novel approach of thermo-electrocatalytic deoxygenation of glycerol at ambient temperature and pressure. The application of elevated temperature within the electrolyte and selective electrolysis of glycerol over electrocatalyst, which also acts as electrode, will allow two-fold deoxygenation to occur within the single cell system. This strategy, therefore, can be a promising alternative to upgrade diverse oxygenated compounds into desired biofuels.

Valorization of waste cooking oil (WCO) to sustainable aviation fuel (SAF) via catalytic hydro-processed esters and fatty acids (HEFA) process: Assessment of catalytic activity and process parameters

SAF is currently more expensive than conventional jet fuels due to higher production costs, limited production capacity, and uncertainty in feedstock availability. As a result, there are several ways to reduce the costs of SAF production in terms of reducing energy and developing new technologies, such as the use of new catalysts and so on. Additionally, when noble group catalysts are expensive and transition group catalysts (mono and di) require higher temperature, pressure, and reaction time for catalytic hydrogenation of WCO then investigate the valorization of WCO to produce 80-90% efficient and effective SAF via the catalytic hydrogenation of the HEFA process by implementation of a newly developed trimetallic Co-Mo-Ni/Al2O3 catalyst followed by optimizing the catalytic activity and reaction conditions are the main aim and objective of this research. Furthermore, this could provide a sustainable solution for disposing of WCO, reducing dependence on fossil fuel, expanding the SAF market, reducing GHGs concerns, and climate change in the aviation industry, and acquiring net zero in 2050.
