| Summary: | Background: Catalytic co-pyrolysis process is an emerging thermochemical pathway to convert multiple wastes,
such as biomass and municipal solid wastes into value added fuels. The ecology would suffer from mishandling of
these materials, leading to landfills and microplastic contamination. However, the co-pyrolysis of the surgical
face mask (SFM) wastes with biomass remains a niche research area.
Methods: The co-pyrolysis performance, kinetics and thermodynamics of oil palm empty fruit bunches (EFB) and
SFM mixture were evaluated via thermogravimetric analysis (TGA) approach at heating rates from 10 to 100 ◦C.
min− 1 with weight ratio of 1:1, 4:1 and 1:4. Additionally, the development of the artificial neural network (ANN)
model to represent the thermal degradation behaviour of the overall catalytic co-pyrolysis process for EFB and
SFM mixtures.
Significant findings: The highest average pyrolysis performance index, Ir value of 8.11 was found in the reaction at
50 ◦C.min− 1
. The weight change, ΔWTGA showed the thermal degradation behaviour of EFB and SFM co-pyrolysis
exhibited predominantly inhibitory characteristics, as the experimental values were higher than the theoretical
values. Moreover, the HZSM-5 catalyst showed great affinity towards the sample matrix, achieving high
reduction of activation energy and difference in enthalpy of 13.54 % and 14.94 %, respectively.
