“…In the cellulase literature, the synergy between these enzymes was anticipated in many studies [65][66][67][68] and several works modeled the enzymatic reactions with discrete rate equations and population balance equations. [69][70][71][72] One population balance study demonstrated the synergy between end-scission and random-scission enzymes, although no recipe for the synergy calculation was provided. 72 In this work, we revisit the second-order PBE developed by Guironnet and Peters.…”

The use of cellulose is hampered by difficulties with breaking up the biopolymer into soluble products. Herein, we show that the impregnation of cellulosic substrates with catalytic amounts of a strong acid (e.g., H(2)SO(4), HCl) is a highly effective strategy for minimizing the contact problem commonly experienced in mechanically assisted, solid-state reactions. Milling the acid-impregnated cellulose fully converts the substrate into water-soluble oligosaccharides within 2 h. In aqueous solution, soluble products are easily hydrolyzed at 130 °C in 1 h, leading to 91 % conversion of the glucan fraction of α-cellulose into glucose, and 96 % of the xylans into xylose. Minor products are glucose dimers (8 %), 5-hydroxymethylfurfural (1 %) and furfural (4 %). Milling practical feedstocks (e.g., wood, sugarcane bagasse, and switchgrass) also results to water-soluble products (oligosaccharides and lignin fragments). The integrated approach (solid-state depolymerization in combination with liquid-phase hydrolysis) could well hold the key to a highly efficient "entry process" in biorefinery schemes.
