Description: There is an interest in using bioethanol as a sustainable energy source. The conversion of carbohydrates to bioethanol through fermentation generally leads to a broth that contains 5-12 wt% of ethanol mixed with water and some other organics. In the ethanol industry, the recovery of ethanol from the fermentation broth to fuel grade is mainly by distillation of fermentation strength ethanol to 95 wt% ethanol-water mixture below the azeotrope (95.6 wt% ethanol), followed by adsorption using molecular sieves to remove the remaining water. However, the process for bioethanol dehydration is costly and disposal of exhausted molecular sieves is a threat to the environment. Adsorption using biosorbents attracts increasingly interest due to low costs and non-toxicity to the environment. Canola meal is abundantly produced as a by-product in canola industry in western Canada. In the present work, adsorption of water and ethanol from liquid phase using canola meal as adsorbent was investigated. The effects of canola meal particle size, temperature, contact time, and water/ethanol concentration on ethanol and water uptake were examined. Experimental results demonstrated that canola meal with particle sizes of 1.18
