Tiivistelmä
This thesis is a part of a project which aims at utilizing fibre sludge from pulp mill as a source of biofuel production. The study concentrates on optimizing one of the processing steps, enzymatic hydrolysis, in converting fibre sludge to bioalcohol.
The aim of the thesis was to find optimum process parameters that enable maximum yield of glucose after performing the enzymatic hydrolysis. For this purpose, a series of experiments with changed process parameters was conducted. Also, enzyme mixes from two different manufacturers were used and the outcome was compared.
As a result, the optimum conditions were determined and a more effective enzyme mix is chosen. However, the outcome of glucose may be increased; therefore, further investigation is needed.
