Delignification Kinetics of Corn Stover with Aqueous Ammonia Soaking Pretreatment
Soaking aqueous ammonia (SAA) pretreatment of corn stover was carried out at three temperatures (30, 50, and 70 oC) and three concentrations of ammonia solution (5, 15, and 25 wt.%). The delignification kinetic model, based on three first-order reactions, was applied to describe the kinetic behavior of lignin removal from corn stover during SAA pretreatment. The first, second, and third terms w...
متن کاملFluid mechanics relevant to flow through pretreatment of cellulosic biomass.
The present study investigates fluid mechanical properties of cellulosic feedstocks relevant to flow through (FT) pretreatment for biological conversion of cellulosic biomass. The results inform identifying conditions for which FT pretreatment can be implemented in a practical context. Measurements of pressure drop across packed beds, viscous compaction and water absorption are reported for mil...
متن کاملCellulosic Biomass Pretreatment and Sugar Yields as a Function of Biomass Particle Size
Three lignocellulosic pretreatment techniques (ammonia fiber expansion, dilute acid and ionic liquid) are compared with respect to saccharification efficiency, particle size and biomass composition. In particular, the effects of switchgrass particle size (32-200) on each pretreatment regime are examined. Physical properties of untreated and pretreated samples are characterized using crystallini...
متن کاملAqueous ammonia soaking (AAS) as a biomass pretreatment method: pilot-scale study with switchgrass, bench-scale use with poplar, and methane potential from anaerobic digestion of pretreated switchgrass
The main objective of this thesis was to evaluate aqueous ammonia soaking (AAS) as a pretreatment method for lignocellulosic biomass preparation for biofuel production, in a variety of settings. This thesis, partially fulfills the Master of Science degree requirement, is prepared in the journal paper format, and includes three papers that have been published in or are prepared for submission to...
متن کاملPretreatment and fractionation of corn stover by soaking in ethanol and aqueous ammonia.
A new process for pretreatment of lignocellulosic biomass, designated the soaking in ethanol and aqueous ammonia (SEAA) process, was developed to improve hemicellulose preservation in solid form. In the SEAA process, an aqueous ammonia solution containing ethanol is used. Corn stover was treated with 15 wt.% ammonia at 1:9 solid-liquid ratio (by weight) at 60 degrees C for 24 h with ethanol add...
