Explorative catalyst screening studies on reforming of glycerol in supercritical water

Biomethanol from Glycerol

“…Carbon balance closure for the reformer is very satisfactorily and was between 95 and 104%. The glycerol conversion was almost complete for all experiments, which is in line with previous work [18,29]. The syngas produced had the following composition range: H 2 /CO/CO 2 /C x H y = 44 -67/1 -21/16 -34/2 -18 vol%, 0.7 ≤ S N ≤ 1.2.…”

“…The differences between pure glycerol and crude glycerin can be mainly attributed to the extent of the progress of the WGS reaction [18]. Relations between the conversion and the gas yield for pure glycerol (A) and crude glycerin (B) [29].…”

“…Catalytic reforming was investigated to improve the quality of the syngas obtained in the noncatalytic reforming experiments for subsequent methanol synthesis. An extensive description of catalytic reforming using five different catalysts is given in literature [29]. The catalytic experiments were conducted at temperatures between 648 to 973 K at pressures between 25.5 -27.0 MPa.…”

“…In these experiments the glycerol reforming is carried out catalytically by using the Ni based catalyst in combination with higher temperatures. All C 2+ hydrocarbons are then reformed and the CH 4 equilibrium concentration decreases (with higher temperatures) yielding a more attractive gas composition [29].…”

“…c Experiment conducted in recycle mode. Glycerol conversion is estimated based on previous work [29].…”
