Esterification of residual palm oil using solid acid catalyst derived from rice husk (2020)
Journal Article
Semilin, V., Balan, W. S., Janaun, J., Chung, C. H., Zhu, Z., Haywood, S. K., …Zein, S. H. (2021). Esterification of residual palm oil using solid acid catalyst derived from rice husk. Journal of hazardous materials, 404(Part B), https://doi.org/10.1016/j.jhazmat.2020.124092

In this study, carbon-silica based acid catalysts derived from rice husks (RH) were successfully synthesised using microwave (MW) technology. The results showed that MW sulphonation produced Sulphur (S) content of 17.2–18.5 times higher than in raw R...

Recovery of oil from palm oil mill effluent using polypropylene micro/nanofiber (2020)
Journal Article
Semilin, V., Janaun, J., Chung, C. H., Touhami, D., Haywood, S. K., Chong, K. P., …Zein, S. H. (2021). Recovery of oil from palm oil mill effluent using polypropylene micro/nanofiber. Journal of hazardous materials, 404, https://doi.org/10.1016/j.jhazmat.2020.124144

Residual palm oil that goes into the river untreated can become detrimental to the environment. Residual oil discharge during milling process into palm oil mill effluent (POME) is unavoidable. About 1 wt% of residual oil in POME causes major problems... Read More about Recovery of oil from palm oil mill effluent using polypropylene micro/nanofiber.

Characterization of rice husk-based catalyst prepared via conventional and microwave carbonisation (2017)
Journal Article
Touhami, D., Zhu, Z., Balan, W. S., Janaun, J., Haywood, S., & Zein, S. (2017). Characterization of rice husk-based catalyst prepared via conventional and microwave carbonisation. Journal of Environmental Chemical Engineering, 5(3), 2388-2394. https://doi.org/10.1016/j.jece.2017.04.020

© 2017 Elsevier Ltd. Carbon-based sulphonated catalysts (CBSCs) were made from rice husk for biodiesel production. The CBSCs were prepared by microwave (MW) and conventional heating processes from the same feedstock. In both heating systems, the prep...

Study of pyridine-mediated electrochemical reduction of CO2 to methanol at high CO2 pressure (2016)
Journal Article
Haywood, S. K., Rybchenko, S. I., Touhami, D., & Wadhawan, J. D. (2016). Study of pyridine-mediated electrochemical reduction of CO2 to methanol at high CO2 pressure. ChemSusChem, 9(13), 1660-1669 . https://doi.org/10.1002/cssc.201600267

© 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim The recently proposed highly efficient route of pyridine-catalyzed CO 2 reduction to methanol was explored on platinum electrodes at high CO 2 pressure. At 55 bar (5.5 MPa) of CO 2 , the bulk elec... Read More about Study of pyridine-mediated electrochemical reduction of CO2 to methanol at high CO2 pressure.
