[Paper]: Extraction of arabinoxylans from wheat bran using hydrothermal processes assisted by heterogeneous catalysts

The extraction/hydrolysis process of arabinoxylans from destarched wheat bran was studied in this work using different mesoporous silica supports and the corresponding RuCl3-based catalysts. The effects of temperature, time, catalyst supports and ruthenium catalysts were investigated and discussed in terms of the arabinoxylans extraction yield and their polymerization degree. Relatively high temperatures (180 ºC), short […]

[Paper]: Bimetallic Ru:Ni/MCM-48 catalysts for the effective hydrogenation of D – glucose into sorbitol

Three different bimetallic Ru:Ni catalysts supported on a mesoporous silica MCM-48 were prepared by consecutive wet impregnations, with a total metal loading of ca. 3 % (w·w-1). Ru:Ni ratios spanned in the range of 0.15 – 1.39 (w·w-1) and were compared with the corresponding monometallic Ni/MCM-48. The catalysts so prepared were characterized by X-Ray Diffraction, […]
