Design and optimization of a crossflow tube reactor system for hydrogen production by combining ethanol steam reforming and water gas shift reaction
Chen, Wei-Hsin; Lu, Chen-Yu; Chou, Wei-Shan; Sharma, Amit Kumar; Ayyadurai, Saravanakumar; Tran, Khanh-Quang (Peer reviewed; Journal article, 2022)Crossflow tube reactors with crossflow configuration are considered a special design for hydrogen production via ethanol steam reforming with less catalyst than conventional packed bed reactors. However, the results showed ... -
Energy-saving drying strategy of spent coffee grounds for co-firing fuel by adding biochar for carbon sequestration to approach net zero
Lee, Kuan-Ting; Tsai, Jai-You; Hoang, Anh Tuan; Chen, Wei-Hsin; Gunarathne, Duleeka Sandamali; Tran, Khanh-Quang; Selvarajoo, Anurita; Goodarzi, Vahabodin (Peer reviewed; Journal article, 2022)Drying is an important but energy-intensive industrial process, while spent coffee grounds can be used as an abundant and potential biomass waste to replace part of the coal consumption for green fuel production and circular ... -
Hydrogen production from methanol partial oxidation through the catalyst prepared using torrefaction liquid products
Chih, Yi-Kai; Chen, Wei-Hsin; Tran, Khanh-Quang (Peer reviewed; Journal article, 2020)This study developed a novel application of torrefaction liquid products (TLPs) for acidic catalyst sol-gel synthesis of SiO2 from tetraethyl orthosilicate (TEOS) to improve the thermal stability of Al2O3 catalyst supporter. ... -
A new design of catalytic tube reactor for hydrogen production from ethanol steam reforming.
Chen, Wei-Hsin; Lu, Chen-Yu; Tran, Khanh-Quang; Lin, Yu-Li; Naqvi, Salman Raza (Peer reviewed; Journal article, 2020)A new design of the catalytic tube system with a crossflow configuration, featured by low catalyst usage and cost, is developed using computational fluid dynamics (CFD). Meanwhile, the kinetics of ethanol steam reforming ... -
Valorisation of Napier Grass and Agricultural Residues via Pyrolysis – A Kinetic Study
Bui, Hau-Huu; Tran, Khanh-Quang; Luengnaruemitchai, Apanee; Seisenbaeva, Gulaim; Naqvi, Salman Raza; Chen, Wei-Hsin (Peer reviewed; Journal article, 2022)Thermal pyrolysis of Thai Napier grass, cassava stalk and rice straw were studied thermogravimetrically, which was followed by a kinetic analysis assuming multiple kinetic schemes and a distributed activation energy model ...
