Abstract Selective catalytic reduction (SCR) systems using solid ammonia carriers like carbamates, carbonates, etc., have gained interest in the recent past for NOx abatement from compression ignition engines. Solid successfully demonstrated their use SCR systems. In this experimental study, thermal dissociation study of ammonium carbonate is made nonisothermal thermogravimetric analysis. Ammon...

Abstract The catalytic conversion of CO2 captured in aqueous media into formate was studied using aluminum-sourced hydrogen a batch reaction system. To do so, the main ammonia-based absorption derivatives: ammonium carbamate, carbonate and bicarbonate sodium were selected as source. performance different species determined under mild hydrothermal conditions (120 °C), Pd/C 5 wt% catalyst. In the...

Liquid–liquid extraction of carbonate and mixed peroxo-carbonate compounds U(VI) Am(III) from Na2CO3 aqueous solutions by methyltrioctylammonium in toluene has been studied. The main patterns effect extractant, Na2CO3, H2O2 concentration on distribution separation have established. Using slope analysis UV–vis spectroscopy, the compositions extractable are established as (R4N)4[UO2(CO3)3], (R4N)...
