How is furfural made?
Furfural is produced by removing water from or dehydrating five-carbon sugars such as xylose and arabinose. These pentose sugars are commonly obtained from the hemicellulose fraction of biomass wastes like cornstalks, corncobs and the husks of peanuts and oats.
What can I do with sugarcane bagasse?
Bagasse is typically used to produce heat and electricity in sugar mills (cogeneration), but can also be used for paper making, as cattle feed and for manufacturing of disposable food containers. Currently, bagasse is mainly used as a fuel in the sugarcane industry to satisfy its own energy requirements.
How much bagasse is produced per ton of sugarcane?
In the specific case of the sugar-energy sector, each ton of sugarcane ground in sugar and ethanol production generates, on an average, 50% moisture, 250–270 kg of bagasse, and more than 200 kg of straw.
How do you extract cellulose from sugarcane bagasse?
Cellulose was extracted from sugarcane bagasse by alkaline extraction with sodium hydroxide followed by delignification/bleaching using sodium chlorite/hexamethylenetetramine system.
What is furfural made from?
What is the composition of furfural reagent?
Furfural is an organic compound with the formula C4H3OCHO. It is a colorless liquid, although commercial samples are often brown….Furfural.

What is the byproduct of sugarcane?
The four main byproducts of the sugarcane industry are cane tops, bagasse, filter muds and molasses (Figure 1).
What is the difference between molasses and bagasse?
Molasses chemical composition is very varied; where, sucrose (60–63%), reducing sugars (3–5%) and trace minerals are the principal compounds (Tellez, 2004; Yepez, 1995). On the other hand, sugarcane bagasse is a residue that remains after sugarcane milling, which is realized for juice extraction (Basanta et al., 2007).
How is electricity produced from bagasse?
Where survey information is not available, bagasse energy production and use can be derived from sugar cane processing statistics. The figure below shows the energy flow in a traditional sugar mill that burns bagasse to generate steam for electricity production, cane crushing and heat.
How much does bagasse cost?
thousand cubic feet, a boiler efficiency of 80% for natural gas and 53.9% for bagasse, one ton of bagasse at 50% moisture content is worth $13, as of January, 2015. Similar calculations reveal that at 32% moisture content the bagasse is worth $22 per ton.
How is fiber extracted from sugarcane?
Sugar cane fiber bundles were extracted from the separated rind of cane stalks using alkaline treatments. The amount of lignin removed depended on alkaline concentration and time and pressure of treatment; agitation and vigorous boiling also affected the lignin removal.
How is cellulose extracted from biomass?
The extraction of cellulose nanofibrils (CNFs) from wood pulp biomass is often done using the TEMPO-mediated oxidation method. Its nanoscale is about 5–60 nm in diameter and many microns in length (Habibi et al., 2010). CNF consists of cellulosic domains i.e., crystalline and amorphous domains.
