Pretreatment of Lignocellulosic Wastes with Aqueous Ammonia and Hydrogen Peroxide |
| 초록 |
The reaction is carried out in a flow-through packed-bed reactor. The process stream is continuously fed into and withdrawn from the reactor. Under this operation mode, the lignin and other extraneous components are separated from the biomass structure preventing recondensation of lignin. Ammonia is then recovered at the end of the process. This process has been proven to be very effective for pretreatment of hardwood and herbaceous substrates. In contrast to these types of substrates substrates, the literature information on biological conversion of softwood is scarce. Perhaps it is due to the fact that softwood is one of the most difficult substrates to degrade biologically. The softwood based feedstocks have high lignin content and dense structure between cellulose fiber and lignin. They exhibit extremely low enzymatic digestibility. Hydrogen peroxide is one of the few delignifying reagents that are environmentally benign. Hydrogen peroxide in alkaline condition promotes rapid oxidative depolymerization of the lignin molecule in lignocellulosic materials. It has been used in the pretreatment of biomass. It has also been tested in our laboratory as a supplementary reagent in the ARP system. |
