Abstract

Hardwood is found out to be more preferable for producing neutral-sulfite semichemical pulp. Cooking at increased values of chemical charge and duration of haulting with final temperature allows to produce semichemical pulp with the biggest output. Semifinished product with maximum characteristics of hardness (resistance to plane compression) is produced at pulp cooking with 40% degree of monosulfite substitution by white liquor.
