Among all N-doped biochars, "the #biochar prepared with corncobπ½ powder, K2CO3Β & urea at 800Β°C showed highest #adsorption ability (5.69 mmol/g at 0Β°C & 1 bar) & selectivity (38.24 at CO2/N2Β = 10/90).Β The biochar also showed excellent thermal stability & cycle performance."

"Notable, correlation analysis showed that ultra-micropores were the decisive factor for #CO2Β #adsorption at low temperatures; nevertheless, the effect of N-doping would gradually appear with the increase of adsorption temperature."

#Adsorption #Breakthrough experiments are so ubiquitous, but there isn't a good reference/review paper that addresses this technique. We wrote this review paper keeping graduate students, new entrants in mind. We hope this will be helpful. Summary in 10 pts.:
1. SET-UP: Minimize dead volume; Control inlet flow & composition; Measure outlet flow &composition;Keep col.dia/part.dia >10, col.len/col.dia>3. Measure pressure drop. Industrial column-adiabatic; Lab-scale- finite heat transfer => Measure temperature inside column.
2. OPERATION- Run expt. until both outlet composition & temperature return to inlet values. Dead volumes affect both residence time and the spread of the breakthrough curve. If dead vol. is significant, do a correction.
