Autor: Bismark Mensah, Boateng Onwona-Agyeman, Frank Nsaful, Isaac Adjaye Aboagye, Nii Longdon Sowah, Prosper Naah Angnunavuri, Vitus Atanga Apalangya

Publikováno v: Heliyon, Vol 10, Iss 4, Pp e25592- (2024)

This work is a comparative study between Shea butter (SB) and treated distillate aromatic extract oil (TDAE) as plasticizers in the vulcanization of natural rubber (NR)- carbon black (CB) vulcanizates (—CB—S—NR—). The plasticized —CB—S—

Publikováno v: Scientific African, Vol 19, Iss , Pp e01501- (2023)

Thermal degradation of acrylonitrile-butadiene rubber (NBR)-graphene oxide (GO)/reduced graphene Oxide (G) composites (NBR-GO/G) was studied in air O2(g) and nitrogen N2(g) media at ∼800°C, using Thermal Gravimetric Analysis (TGA/DTG). The char yi

Investigating the Effect of Curing Activators on the Cure Kinetics of Acrylonitrile–Butadiene Rubber Filled with Graphene Oxide and Reduced Graphene Oxides Nanocomposites

Autor: Bismark Mensah, Boateng Onwona-Agyeman, Johnson Kwame Efavi, Ralph Abakah Ofor, Mawufemor Zigah, Joyce Koranteng, Maxwell Karikari, Frank Nsaful, Daniel Akwei Addo

Publikováno v: International Journal of Polymer Science, Vol 2023 (2023)

For the first time, acrylonitrile–butadiene rubber (NBR)–graphene oxide (GO) and reduced graphene oxide (rGO) composites were prepared without cure activators: zinc oxide/stearic acid (ZnO/SA) and studied. The vulcanization characteristics of the

Lignocellulose thermal pretreatment and its effect on fuel properties and composition of the condensable products (tar precursors) from char devolatilization for coal substitution in gasification application

Autor: Frank Nsaful, François-Xavier Collard, Johann F. Görgens

Publikováno v: Fuel Processing Technology. 179:334-343

To establish the potential of thermally pretreated biomass as fuel for coal replacement in applications such as gasification, the fuel properties (higher heating value, elemental and proximate analyses) and the composition of char devolatilization pr

Comparison of combustion and pyrolysis for energy generation in a sugarcane mill

Autor: Frank Nsaful, Johannes H. Knoetze, Johann F. Görgens

Publikováno v: Energy Conversion and Management. 74:524-534

The study focusses on the comparison of biomass to energy conversion process (BMECP) models to convert sugar mill biomass (bagasse) into energy products via combustion and pyrolysis as thermochemical pathways. Bagasse was converted to steam and elect
