摘要

Pulping and bleaching of Central Indian Hardwoods (Bastar area) was carried out on three composite samples based on different diameter classes and on the forest composite sample including all diameter classes. All the above mentioned samples could be pulped satisfactorily and the pulps could be bleached by the CEHH sequence to brightness levels between 74.7 and 78.1%. The pulp evaluation data had revealed that the pulps from larger diameter classes were slightly inferior in strength characteristics when compared with others. In all cases, a slight drop in strength properties was observed on bleaching. The spent liquors from the above mentioned cooks were studied for rise in viscosity and precipitation characteristics with concentration on evaporation. It was observed that the black liquor from forest composite cook could be evaporated to higher concentrations without precipitation than the black liquor for composite samples of diameter classes.
