Hydrogen production by glycerol dry reforming over rhenium promoted Ni-based catalyst supported on Santa Barbara Amorphous 15 (SBA-15)

Advanced zeolite and ordered mesoporous silica-based catalysts for the conversion of CO2to chemicals and fuels

“…The data on dry reforming of glycerol are limited in the literature, and we found only one reference exploring the activity of Ni/SBA-15 catalysts. 978 The most used catalysts for GDR, as it occurs for numerous CO 2 conversion processes at high temperatures, are Ni-based catalysts due to the Ni lower price, high catalytic activity and availability. Besides Ni-based catalysts suffer high deactivation due to metal sintering and coke formation, different studies explored the catalytic performance of noble metals since they are more stable against sintering and coke formation at high temperatures.…”

Preparation of a Nanostructured Ni/CaO·Al2O3 Catalyst for Syngas Production via Glycerol Dry Reforming: Role of the Preparation Method

“…Several research studies have been conducted (see refs 13−16) and have been developed to offer heterogeneous catalysts for syngas production via the DRgly reaction. 17 Lee et al 18 suggested the cement clinker as a catalyst support for the Ni catalyst in the DR-gly process. They reported an increase in nickel loading from 5 to 20 wt % improving the specific surface area of the catalysts from 0.6 to 18 m 2 g −1 .…”

“…The DR-gly reaction requires a good performance catalyst to cleave C–H and C–C bonds. Several research studies have been conducted (see refs − ) and have been developed to offer heterogeneous catalysts for syngas production via the DR-gly reaction . Lee et al suggested the cement clinker as a catalyst support for the Ni catalyst in the DR-gly process.…”

A highly active and stable Ru catalyst for syngas production via glycerol dry reforming: Unraveling the interplay between support material and the active sites

“…Majority of these studies involved investigation of Ni-based catalysts primarily due to their inherently high activity in dry and steam reforming of hydrocarbons [9,[16][17][18]. Monometallic (Ni/γ-Al 2 O 3 [19], Ni/ZrO 2 [20], Ni/CaO [20], Ni/SBA-15 [21], Ni/CaO-SiO 2 [22,23], mesoporous Ni/MgO.Al 2 O 3 [24] and bimetallic (La-Ni/Al 2 O 3 [25][26][27], Ag-Ni/Al 2 O 3 [28], Ag-Ni/SiO 2 [29], Re-Ni/CaO [20], Re-Ni/SBA-15 [21] catalysts were studied within 600-900 • C, with molar ratios of CO 2 /G = 0.5-5 under atmospheric pressure, and at residence times between 1.4 and 7.2 ×10 4 ml/g cat .h yielding glycerol conversion and H 2 /CO molar ratios ranging between 3% and 100% and 0.5-2, respectively. Some of these former studies [22,25] also reported 72 h time--on-stream catalytic stability results which commonly indicated partial (i.e., >25%) loss in glycerol conversion to gaseous products or complete deactivation of the Ni-based catalysts.…”
