AMMONIA FIBER EXPLOSION (AFEX) PRETREATMENT OF LIGNOCELLULOSE Conference Paper

abstract

• The Ammonia Fiber Explosion (AFEX) process treats lignocellulose with high-pressure liquid ammonia and then explosively releases the pressure. The combined chemical effect (cellulose decrystallization) and physical effect (increased accessible surface area) dramatically increase lignocellulose susceptibility to enzymatic attack. There are many adjustable parameters in the AFEX process: ammonia loading, water loading, temperature, time, blowdown pressure, number of treatments, and particle size. The effect of these parameters on enzymatic susceptibility was explored for two collected agricultural residues: bagasse and kenaf core. Nearly quantitative sugar yields have been demonstrated for all materials using a very low enzyme loading (5 IU/g).
