Acylation of anisole with benzoyl chloride over rapidly synthesized fly ash–based hbea zeolite
Ameh, Alechine E.; Musyoka, Nicholas M.; Oyekola, Oluwaseun (Frontiers Media, 2021)Stable HBEA zeolite with high surface area and strong acid sites was synthesized from coal fly ash–based silica extract via indirect hydrothermal synthesis. The rapid HBEA hydrothermal crystallization times of 8, 10, and ... -
Fusion-assisted hydrothermal synthesis and post-synthesis modification of mesoporous hydroxy sodalite zeolite prepared from waste coal fly ash for biodiesel production
Shabani, Juvet Malonda; Ameh, Alechine E.; Petrik, Leslie (MDPI, 2022)Increases in biodiesel prices remains a challenge, mainly due to the high cost of conventional oil feedstocks used during biodiesel production and the challenges associated with using homogeneous catalysts in the process. ... -
Transformation of fly ash based nanosilica extract to BEA zeolite and its durability in hot liquid
Ameh, Alechine E.; Fatoba, O. O.; Musyoka, Nicholas M. (Elsevier, 2020)Power generation in South Africa relies heavily on the combustion of coal and during this process, coal fly ash (CFA) is generated as by-product, which raises several environmental issues. The transformation of CFA into a ...
