The raw CFA can be converted to ANA or FAU primary zeolite by an “assembly” step and CHA resultant zeolite by the subsequent “reassembly” step in the hydrothermal alkaline solution. We focus on the mechanism of the CFA-to-CHA process and the NH3-SCR performance of the Cu-SSZ-13 zeolite. The synthesized Cu-SSZ-13 possesses a standard CHA-type framework structure and controllable Al placement. It shows a high NO conversion rate that is comparable to the commercial Cu-SSZ-13. This approach enables the facile transformation of raw CFA waste to Cu-SSZ-13 zeolite with desirable composition and catalytic property, which provides insights into the formation mechanism during the interzeolite transformations process.]]> Mon 14 Nov 2022 15:34:54 AEDT ]]> Effect of temperature and gasification gas from char on the reactions of volatiles generated from rapid pyrolysis of a low rank coal https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:37929 Mon 05 Jul 2021 13:26:41 AEST ]]> Effect of volatiles' reaction on coking of tar during pyrolysis of Naomaohu coal in a downer-bed reactor https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:37933 103 °C/min) and temperatures (550-800 °C). The tar composition was analyzed by gas chromatography with the simulated distillation method and a comprehensive two-dimensional gas chromatography/mass spectrometry. The structure of coke suspended in tar (Coke-S) and char was characterized by electron spin resonance, Raman and thermogravimetry. The reaction of volatiles during coal pyrolysis is more significant in the downer-bed reactor, due to the increased interaction between different volatile radical fragments or with char, leading to increased coke yield and lower tar quality. In addition, the volatile radical fragments are dominated by the core structure of aromatic carbon at higher than 650 °C in the downer-bed reactor. In the second thermal field in the downer-bed reactor, Coke-S produced by these fragments has more macromolecular structures and greater stability than char obtained at the same temperature.]]> Mon 05 Jul 2021 13:21:44 AEST ]]> A magnetically recoverable Fe₃O₄-NH₂-Pd sorbent for capture of mercury from coal derived fuel gas https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:30802 Fri 24 Aug 2018 08:58:46 AEST ]]> Catalytic upgrading of coal pyrolysis volatiles by porous carbon materials derived from the blend of biochar and coal https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:38270 Fri 20 Aug 2021 12:58:53 AEST ]]> Impact of chemical structure of coal on coke quality produced by coals in the similar category https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:49137 Fri 05 May 2023 12:00:41 AEST ]]> Coal-based sulfur hybrid sorbent for removal of Hg<sup>0</sup> from flue gas.
