Catalyzed-Mea conversion of Agro-biomass to paper-pulp: Influence of pulping additives and synergy effect on pulp screened yield

In this research work, the effect of three (3) pulping additives such as polysulfide, Anthraquinone and surfactant used in monoethanolamine (MEA) agro-biomass, their possible interactions synergy on pulp screened yield were investigated. The conditions digester adjusted so that experimental design considered following factors levels: 75% MEA charge, 150oC cooking temperature, 90minutes time, 4 to 1Liquor- Biomass ratio. Factor 1: 0, 0.25 0.5% Surfactant 2: 2.0 4.0% polysulfide 3: anthraquinone charge. Agro-biomass was evaluated terms yield. Heating time ranged from 5 45minutes maximum did not exceed 90minutes, liquor biomass ratio 1 Liquor charge MEA. for with 4% Polysulfide (PS) dosage without inclusion highest (59.08%) all twenty seven (27) runs, but furnished reject (12.26%) an unimpressive 46.82% standing amongst least outcomes. 0.25% (AQ) a total 50.32%, 50.03% minimal 0.29 showing be more efficient than use polysulfide. Monoethanolamine (Surf.) other i.e. AQ PS achieved 51.12% only 0.33% furnishing (50.79%) thereby efficiency investigated study base single use. However, result obtained combination (52.43) 4.23% scenario E, experiment No. 15, involving surfactant, best synergistic effect.
