In sulfite pulps

ChemicalRecope . There are advantages and disadvantages to each of the base systems employed in sulfite pulping (see Table 4). Each has its own potential recovery systems except the calcium system, which is obsolete. Calcium-based Hquors can be burned, but scaling problems are severe, and conversion of the calcium sulfate to CaO is not economical. [Pg.273]

During the course of his stay in Darmstadt, Heuser had applied for at least ten patents, seven of which were granted while he still held the Chair of Cellulose Chemistry. The other three were granted soon thereafter. The patents (in some cases taken out with an individual coworker) dealt with such varied subjects as sizing, the production of methanol, tar, carbon, and gaseous fuels obtained in the pyrolysis of hgnin, the permanent elimination of reddening in sulfite pulps, and the production of protocatechuic acid and pyrocatechol. [Pg.5]
