Valorization of hazardous COVID-19 mask waste while minimizing hazardous byproducts using catalytic gasification

Autor: Sumin Pyo, Im-Hack Lee, Young-Kwon Park, Gwang Hoon Rhee, Hocheol Song, Jechan Lee, Young-Min Kim, Chang Hyun Ko, Abid Farooq

Publikováno v: Journal of hazardous materials. 423

This study proposes a method to valorize hazardous waste such as used COVID-19 face mask via catalytic gasification over Ni-loaded ZSM-5 type zeolites. The 25% Ni was found as an optimal loading on ZSM-5 in terms of H2 production. Among different zeo

Mini review on H2 production from electrochemical water splitting according to special nanostructured morphology of electrocatalysts

Autor: Young-Kwon Park, Gwang Hoon Rhee, Sang-Chul Jung, Jung Eun Lee, Kun-Yi Andrew Lin, Ki-Joon Jeon, Im Hack Lee, Pau Loke Show, Yong Jun Choi

Publikováno v: Fuel. 308:122048

Hydrogen is one of the most promising alternative energy resources of fossil fuels. Among the many ways to generate hydrogen gas, electrochemical water splitting is more feasible and renewable. Compared to processes using solar energy for a specific

Suppression of the hazardous substances in catalytically upgraded bio-heavy oil as a precautious measure for clean air pollution controls

Autor: Young-Kwon Park, Gwang Hoon Rhee, Jechan Lee, Y.-K. Park, Im Hack Lee, Sumin Pyo, Young-Min Kim, Sang-Chul Jung, Yong Jun Choi

Publikováno v: Journal of Hazardous Materials. 421:126732

Bio-heavy oil (BHO) is a renewable fuel, but its efficient use is problematic because its combustion may emit hazardous air pollutants (e.g., polycyclic aromatic hydrocarbon (PAH) compounds, NOx, and SOx). Herein, catalytic fast pyrolysis over HZSM-5
