Fast Pyrolysis Characteristics of Sugarcane Bagasse Hemicellulose
The pyrolysis characteristics of sugarcane bagasse hemicellulose were investigated using a tubular furnace. The total gas yield and the releasing behavior of the main gas products were measured by GC analysis. The liquid products were analyzed by GC-MS and ion chromatography. The chars were investigated by elemental analysis and proximate analysis. The volatile remaining in the char extracted b...
متن کاملAcid hydrolysis of sugarcane bagasse for lactic acid production.
In order to use sugarcane bagasse as a substrate for lactic acid production, optimum conditions for acid hydrolysis of the bagasse were investigated. After lignin extraction, the conditions were varied in terms of hydrochloric (HCl) or sulfuric (H(2)SO(4)) concentration (0.5-5%, v/v), reaction time (1-5h) and incubation temperature (90-120 degrees C). The maximum catalytic efficiency (E) was 10...
متن کاملExtraction of Hemicellulose and Lignin from Sugarcane Bagasse for Biopolymer Films: Green Process
A hemicellulose is any of several heteropolymers , such as arabinoxylans, present along with cellulose in almost all plant cell walls. Hemicellulose has a random, amorphous structure with little strength. It is easily hydrolyzed by dilute acid or base as well as myriad hemicellulase enzymes. In this study, lignin and hemicellulose was extracted from sugarcane bagasse using the ammonium hydrolys...
متن کاملIncreased enzymatic hydrolysis of sugarcane bagasse from enzyme recycling
BACKGROUND Development of efficient methods for production of renewable fuels from lignocellulosic biomass is necessary to maximize yields and reduce operating costs. One of the main challenges to industrial application of the lignocellulosic conversion process is the high costs of cellulolytic enzymes. Recycling of enzymes may present a potential solution to alleviate this problem. In the pres...
متن کاملKinetic Study of the Enzymatic Hydrolysis of Sugarcane Bagasse
This work presents a kinetic study of the enzymatic hydrolysis of three cellulosic substrates: filter paper (FP), used as a low recalcitrance substrate model; steam exploded sugarcane bagasse (SB); and weak acid pretreated SB (1:20 dry bagasse:H2SO4 solution 1% w/w), the last two delignified with 4% NaOH (w/w). The influence of substrate concentration was assessed in hydrolysis experiments in a...
