Resumen:
|
The objective of this work was to evaluate the effect of particle size on steam-explosion pretreatment of herbaceous lignocellulosic biomass. Hemicellulose and cellulose recovery, and effectiveness of enzymic hydrolysis of the cellulosic residue is presented for steam-explosion pretreatment of an agriculture residue (Brassica carinata ) using different particle sizes. The parameters tested were: particle size (2-5, 5-8 and 8-12 mm), temperature (190 and 210 ºC), and residence time (4 and 8 min). The compositional analysis of filtrate and water insoluble fibre after pretreatment and enzymic digestibility data are presented. Larger steam-exploded particle (8-12 mm) results in higher cellulose and enzymic digestibilities. The use of very small particles in steam explosion would not be desirable in optimising the effectiveness of the process improving economy.
