WebMar 29, 2024 · Replacing fossil fuel for bioethanol has a long and successful history in Brazil. Ethanol has been used as an additive to gasoline since the 1930s, and after the Proalcool Program in the 1970s, car engines were adapted to run with ethanol only. The total amount of ethanol-fueled vehicles at one point reached 5 million; how The market … WebBioethanol production from algae is a promising approach that resolves problems associated with biofuel production from land biomass, such as bioethanol– food conflicts and the indirect land use change. However, it presents several technical difficulties because existing ethanologenic microbes can neither degrade alginate, a major component of …

WebIn addition, utilization of lignocellulosic materials in bioethanol production is the most viable pathway from an environmental point of view. This paper reviews the current status and technologies involved in bioethanol production and the properties and engine performance from various biomass feedstocks which are the recommended sustainable ... WebThis study gives insight into different biomass pre-treatment and biofuel production methods, especially biogas, biohydrogen, and bioethanol. Furthermore, the review explores the comparative assessment of biological pretreatment of algal biomass and shows that biological processes can result in better biofuel yield from algal biomass. iris charity

WebOct 12, 2024 · Generally, the bioethanol production process from lignocellulosic biomass consists of four main steps, which are pretreatment, hydrolysis, fermentation, and separation . The pretreatment step is used to remove lignin and alter cellulose structures by increasing cellulose accessibility for a further hydrolysis process. WebThe maximum experimental bioethanol yield obtained after applying ANN-GA was 0.242 ± 0.002 g/g RS, which was in close proximity with the predicted value (0.239 g/g RS). Hence, the developed ANN-GA model can be applied as an efficient approach for predicting the fermentative bioethanol production from macroalgal biomass. WebSep 11, 2024 · The existing energy demand, fluctuating oil prices and repercussions due to usage of fossil fuels have enhanced the requirement for alternative energy sources. Bioethanol derived from cereal crops serve as a promising alternative to conventional gasoline owing to the advantages of feedstock availability, reduction in production costs … iris charities
