DS.07.02b - Resource recovery from gasification residues

The data set contains the results from the biomass char and biomass ash leaching experiments, mainly the results of the elemental analysis of the leachate obtained at different leaching conditions. Data is stored in a MS Access database format. It includes a graphical interface (form) for data selection / filtering and drawing of simple charts. Types of substrates: clean wood char, demolition wood char, miscanthus (mix) char, hay char, switchgrass char, miscanthus (mix) ash. Types of leaching agents used: demi water, hydrochloric acid, citric acid, oxalic acid, ammonium acetate, sodium hydroxide, water peroxide Leaching temperatures: 25°C, 60°C, 120°C, 160°C, 200°C Leaching pressures: ambient pressure, 10 bar, 107 bar Leaching ratios (Solid:Liqiud): 0.05, 0.1, 0.2 Leaching systems: open batch system (beaker), pressurized batch reactor, advanced extraction system (ASE) Attention: not all combinations of the above leaching parameters have been tested, therefore some combinations may yield no data.
