Abstract:
... BACKGROUND: Bioelectrochemical systems (BESs) are capable of recovery of metals at a cathode through oxidation of organic substrate at an anode. Recently, also hydrogen gas was used as an electron donor for recovery of copper in BESs. Oxidation of hydrogen gas produced a current density of 0.8 A m‐² and combined with Cu²⁺ reduction at the cathode, produced 0.25 W m‐². The main factor limiting curr ...

Abstract:
... BACKGROUND: Methanol to dimethyl ether (MTD) is considered one of the main routes for the production of clean bio‐fuel. The effect of copper loading on the catalytic performance of different phases of alumina that formed by calcination at two different temperatures was examined for the dehydration of methanol to dimethyl ether (DME). RESULTS: A range of Cu loadings of (1, 2, 4, 6, 10 and 15% Cu wt ...
