Amaranth lignocellulose as feedstock for bioethanol production: effect of microwave-assisted alkaline pretreatment on reducing sugar yield
Marx, S.; Xaba, N.; Chiyanzu, I. (ETA-Florence Renewable Energies, 2014)A new class of lignocellulose derived from amaranth (Amaranthus Cruentus) represents a potential feedstock for bioethanol production. The lignocellulose material can be pretreated to yield high monomeric sugar concentrations ... -
Fuel ethanol production from sweet sorghum bagasse using microwave irradiation
Marx, S.; Chiyanzu, I.; Ndaba, B.; Schabort, C.J. (ETA-Florence Renewable Energies, 2013)Sweet sorghum is a hardy crop that can be grown on marginal land and can provide both food and energy in an integrated food and energy system. Lignocellulose rich sweet sorghum bagasse (solid left over after starch and ... -
Influence of reaction atmosphere and solvent on biochar yield and characteristics
Marx, S.; Chiyanzu, I.; Piyo, N. (Elsevier, 2014)Sunflower husks were converted to biochar via thermochemical liquefaction in different solvents and reaction atmospheres. Highest biochar yields obtained was 574 g kg−1 husks. Surface area of the produced chars and evolution ... -
Preparation of polyurethane from lignin and crude glycerol
Muller, L.C.; Marx, S.; Chiyanzu, I.; Vosloo, H. (ETA-Florence Renewable Energies, 2015)Polyurethane foam (PUF) was prepared by a novel approach, using a renewable polyol derived from only biofuel production by-products, lignin and crude glycerol. This could potentially be a high value bio-refinery application ...
