Accelerating biofuel production has been promoted as an opportunity to enhance energy security, offset greenhousegas emissions and support rural economies. However, large uncertainties remain in the impacts of biofuels on air quality and climate1,2. Sugar-cane ethanol is one of the most widely used biofuels, and Brazil is its largest producer3. Here we use a life-cycle approach to produce spati...

The deficiency in existing sugar cane crystallization automatic control system is difficult to measure some key parameters on line, such as mother liquor supersaturation, mother liquor purity, crystal content and crystal size distribution. Controlling brix with PID can only reflect the massecuite concentration of sugar cane crystallization process, but it is hard to guarantee the crystal qualit...

Sugarcane bagasse contains cellulose, lignin and hemicellulose, 39-42%, 20-25% and 25-27% respectively. So it is can be used as a sugar source in many processes. Lignin and hemicellulose must be removed before hydrolysis of cellulose. Several different pretreatment approaches have been studied. The purpose of this research is comparison of acid, ozone and combination of ozone-acid as pretreatme...

The nutritional status, juice quality and sugar production of sugarcane varieties RB867515 RB92579 were evaluated in the cane-plant cycle, as a function magnesium doses applied at bottom planting furrow. study, installed soil with Mg content equal to 0.61 cmolc dm-3, was conducted an experimental design randomized blocks four replications. study 2 x 5 factorial: two varieties: RB92579, five mag...

An effective extraction of the fiberized cane juice has been obtained from a prepared extraction column. Oligosaccharides co~nposed of glucose and fructose were found in both cane juice and in raw sugar. The oligosaccharides found In the juice and raw sugar were probably produced by enzymatic or bacterial reactions occurring in cane which had had a delay of 24 h or Inore between cutting and pro...

The increasing worldwide concern regarding environmental issues, in particular after the consistent reports published by the Intergovernmental Panel on Climate Change – IPCC, has significantly stimulated the production of biofuels. Among these biofuels, the ethanol produced from sugar cane is considered to be of particular importance. Currently, Brazil is the world's largest producer of sugar c...
