Economic evaluation of enzymatic hydrolysis of phenol-pretreated wheat straw

Forskningsoutput: TidskriftsbidragArtikel i vetenskaplig tidskrift

Abstract

Experimental data from the enzymatic hydrolysis of phenol-pretreated Swedish wheat straw have been used to evaluate the cost fractions of capital and utility, enzyme, and raw material. Two different raw material prices and varying enzyme prices have been used. The evaluation is based on an empirical model for the enzymatic hydrolysis and a computer program where utility and equipment, enzyme, and raw material prices can be varied. The optimal residence time for the enzymatic hydrolysis is in the range of 70–110 h. A fed-batch procedure with substrate concentrations higher than 10% oven-dried material (ODM) and enzyme concentrations in the range (6–10) · 106 FPU/ton ODM should be used.
