Abstract

Eucalyptus wood samples were delignified with HCl-catalysed acetic acid solutions under selected experimental conditions and treated with NaClO solutions. The solid residues obtained were employed as substrates for enzymatic hydrolysis. The NaClO concentration used in the pretreatment step, the liquor/solid ratio and the enzyme/substrate ratio were considered as operational variables. The experimental data allowed the development of generalized kinetic models which provided the necessary information for design calculations. The operational conditions were compared from an engineering viewpoint on the basis of economic estimates. Optimum conditions were established from these estimates.
