Microwave-based extractive metallurgy to obtain pure ...

Dec 01, 2021 It has been pointed out that the apparent activation energy in the chemical reaction can be reduced by using microwave-based heating to obtain pure metals through both smelting and recycling (a 52.4% reduction in the production of virgin iron metal (Huang et al., 2012) and 64.2% reduction in the production of recycled zinc metal from EAFD ...

Microwave catalytic reactor for upgrading stranded shale ...

Feb 02, 2019 A microwave fixed-bed reactor (MWFB) was used and its performance was compared to a conventional thermal fixed-bed reactor (CTFB). Over 80 % ethane conversion was achieved under microwave irradiation mode at 375 C. Here, to achieve the same ethane conversion conventionally, the reaction temperature had to be elevated to 660 C in the CTFB.

Benefits of Microwave Reactors

Microwave reactors are equipped with pressure sealing technology, which means heating conditions above reflux are often used in microwaves. The speed at which it can reduce reaction times can be found by applying the Arrhenius law/equation: For every increase of 10 C, the reaction time is cut in half. For example, a reaction that may take a ...
