Production of bioethanol, methane and heat from sugarcane

Production of bioethanol, methane and heat from sugarcane

About this site

Sep 01, 2011  Based on the above considerations, the bagasse biorefinery concept was developed to produce biofuel (bioethanol) and the process effluents were characterized and utilized for the production of additional biofuel (methane) and power (lignin and/or enzymatic hydrolysis residue) to improve the overall recovery of bioenergy from sugarcane.

7.2 Sugarcane Ethanol Production. Production of ethanol from corn will be discussed in the next section; this section will focus on sugarcane ethanol production. So, what needs to be done to get the sugar from sugarcane? The first step is sugarcane harvesting. Much of the harvesting is done with manual labor, particularly in many tropical regions.

Furthermore, while steam explosion is needed for efficient enzymatic saccharification and ethanol production, methane production may take place without such a pretreatment. However, while a process without pretreatment reduces the final methane yield by a modest 21 %, there is a large negative effect on the speed of the digestion process (Fig. 4).

Use of bioethanol for sustainable electrical energy production

energy balance. Production of bioethanol from sugarcane returns about 8 units of energy for each unit expended compared to corn which only returns about 1.34 units of fuel energy for each unit of energy expended [4]. This fact makes more energetically efficient the bioethanol from sugarcane with the existing technology. 3.

Producing bio-ethanol from residues and wastes

nol). currently, bio-ethanol is produced mainly from sugar or starch rich food crops; i.e. corn in the US, sugar cane in Brazil and a mix of wheat, sugar beets, barley and corn in the EU. 3 crop-based bio-ethanol has proven somewhat controversial due to concerns about energy balances, life cycle co 2 emissions and compe-tition with food production.
