Simulation of dilute acid hydrolysis of lignocellulosic materials

The dilute acid hydrolysis of lignocellulosic material is an important part of producing valuable chemicals from such Lignocellulosic materials. Penetration of acid into solid phase could be a rate determining step in this process that depends on type and size of substrate, concentration of acid and operating conditions. In this paper we modeled this penetration in four more common Lignocellulosic materials consisting of bagasse,corn stover , rice straw and yellow Poplar. In each condition we found critical sizes.For materials with coarser sizes diffusion is the rate determining step.
