Optimising the (Microwave) Hydrothermal Pretreatment of Brewers Spent Grains for Bioethanol Production
Table 3
Experimental design used to simultaneously evaluate the impacts of variation of the % solids loading and reaction time during microwave based autohydrolytical pretreatment of BSG at 200°C according to a D-optimal design space. Autohydrolytical pretreatment utilized a Monowave 300 microwave synthesis reactor with G30 vessels (Anton Parr).

D-optimal experimental design created using DesignExpert (Stat-Ease, USA) using a collection of reaction combinations (temperatures and times) from which the D-optimal algorithm chose the treatment combinations to include in the design. This reduced the total number of experiments needed to be conducted from that of a full factorial experimental design. |
