The influence of independent variables in the pulping of wheat straw by use of an ethanol-acetone-water mixture [processing temperature and time, ethanol/(ethanol+acetone) value and (ethanol+acetone)/(ethanol+acetone+water) value] and of the number of PFI beating revolutions to which the pulp was subjected, on the properties of the resulting pulp (yield and Shopper-Riegler index) and of the paper...
Pulp obtained by kraft pulping of olive tree wood was used to make paper sheets. A central composite design was used to examine the influence of pulping variables (temperature, time, active alkali concentration, sulfidity and liquor/wood), and of the number of PFI beating revolutions to which the pulp was subjected on the Shopper-Riegler index of the pulp and the breaking length, stretch, burst index...
