Abstract

A method for production of straw soda-semichemical pulp includes addition to boiling apparatus of straw chips and boiling solution with following straw boiling. Boiling is performed at a temperature of 145-165 °C for 10-30 minutes with consumption of total alkali from 4 to 8 % in units of NaO from weight of absolutely dry raw material. Active boiling reagent is sodium hydroxide.
