Bioethanol production from date fruit waste and its usage in petrol engine / Mazen Abdullatif Alzain

Biofuel is biodegradable, nontoxic and suitable substitute for fossil fuels, and capable to reduce greenhouse gas like CO2, CO, HC and NOX emissions. The study investigated the use of waste date from date palm tree (Phoenix dactylifera) as a source of bio-ethanol production that could be used as a f...

The study investigated the use of waste date from date palm tree (Phoenix dactylifera) as a source of bio-ethanol production that could be used as a fuel. The bioethanol was produced by fermentation process using the waste dates as a substrates for yeast and enzymes such as cellulase and amylase. The effects of different fermentation parameters such as yeast concentration, pH, temperatures, fermentation periods, water content and substrate components on bioethanol production were investigated. From the results, the maximum yield of bioethanol (25%) was achieved at Yeast concentration of 5g/l under pH 5.8 at 28°C for 5 days.
