Abstract

At the optimum level of severity, the aqueous extraction of sugarcane bagasse, an abundant agricultural resdue, gave, depending on the degree of comminution, 60% to 89% yield of xylose, most of it in the form of a water soluble xylan. A process for producing xylose‐rich syrups was conceived and tested, consisting of aqueous extraction, acid hydrolysis of the concentrated aqueous extract centrifugal clarification of the hydrolysate, and recovery of the acid by continuous ion exclusion. The cost estimate indicates operating costs on the order of $0.12 to $0.15/kg xylose, in the form of xylose‐rich molasses. Β© 1995 John Wiley & Sons, Inc.

## Abstract Sugarcane is among the principal agricultural crops cultivated in tropical countries. The annual world production of sugarcane is ∼1.6 billion tons, and it generates ∼279 million metric tons (MMT) of biomass residues (bagasse and leaves). Sugarcane residues, particularly sugarcane bagas
