Abstract

Plantain pseudostem has little application in Africa and constitute major domestic waste and often problematic to manage. It however contains a high content of lignocellulose that can be used for production of pulp. With the geometric decline of feedstock for pulp production due to dwindling wood resources, plantain pseudostem becomes a ready alternative. This study developed design models for batch reactor for the plantain pulping process under isothermal, non-isothermal and adiabatic conditions respectively using the principle of conservation of mass and energy balance. The simulation of the developed design equations yielded a close convergence with the experimental model, analysis with close range absolute deviation value. The delignification of plantain pseudostem showed maximum yield of lignin product as 5.20 ml/l, 0.81 mol/l and 0.20 mol/l at reaction time of 0.173 hours, 1.11 hours and 4.52 hours for isothermal, non-isothermal and adiabatic batch reactors respectively. The study strongly recommends for investigation of plantain pulping, giving its good prospects as cheap alternative source for pulp production.
