Oxidative Steam Reforming of Raw Bio-Oil over Supported and Bulk Ni Catalysts for Hydrogen Production

et al. 2018

Several Ni catalysts of supported (on La 2 O 3 -αAl 2 O 3 , CeO 2 , and CeO 2 -ZrO 2 ) or bulk types (Ni-La perovskites and NiAl 2 O 4 spinel) have been tested in the oxidative steam reforming (OSR) of raw bio-oil, and special attention has been paid to the catalysts' regenerability by means of studies on reaction-regeneration cycles. The experimental set-up consists of two units in series, for the separation of pyrolytic lignin in the first step (at 500 • C) and the on line OSR of the remaining oxygenates in a fluidized bed reactor at 700 • C. The spent catalysts have been characterized by N 2 adsorption-desorption, X-ray diffraction and temperature programmed reduction, and temperature programmed oxidation (TPO). The results reveal that among the supported catalysts, the best balance between activity-H 2 selectivity-stability corresponds to Ni/La 2 O 3 -αAl 2 O 3 , due to its smaller Ni 0 particle size. Additionally, it is more selective to H 2 than perovskite catalysts and more stable than both perovskites and the spinel catalyst. However, the activity of the bulk NiAl 2 O 4 spinel catalyst can be completely recovered after regeneration by coke combustion at 850 • C because the spinel structure is completely recovered, which facilitates the dispersion of Ni in the reduction step prior to reaction. Consequently, this catalyst is suitable for the OSR at a higher scale in reaction-regeneration cycles.

“…All such definitions have been put forth for approval in ASHRAE Technical Committees, namely Exergy Analysis for Sustainable Buildings and Terminology based on [48][49][50][51]. In Table 1, related definitions are also harmonized based on above Equation (9) or Equation (13). Based on Table 1, for example, a nearly Zero Exergy Building (nZEXB) is a building or building cluster that is connected to the district returning at least 80% of the total exergy of heat and power to the district as the total exergy of heat and power supplied from the district annually.…”

“…Such improvements are further represented in the EDR values based on Equation (13) so that the exergetic advantages of these options are compared to reductions in CO 2 emissions over the reference case. In particular, while the reference case has no reduction (EDR = 0), the evaluated options represent incremental or significant improvements in EDR values when compared with CO 2base .…”

Nabgana et al [13] overviewed developments in hydrogen production from biomass using steam reforming. In addition, Qolipour et al [14] compared options to produce hydrogen from wind power plants, PV, and hybrid PV-wind power plants, of which the latter was found to be more feasible.…”

Abstract:The energy base of urban settlements requires greater integration of renewable energy sources. This study presents a "hydrogen city" model with two cycles at the district and building levels. The main cycle comprises of hydrogen gas production, hydrogen storage, and a hydrogen distribution network. The electrolysis of water is based on surplus power from wind turbines and third-generation solar photovoltaic thermal panels. Hydrogen is then used in central fuel cells to meet the power demand of urban infrastructure. Hydrogen-enriched biogas that is generated from city wastes supplements this approach. The second cycle is the hydrogen flow in each low-exergy building that is connected to the hydrogen distribution network to supply domestic fuel cells. Make-up water for fuel cells includes treated wastewater to complete an energy-water nexus. The analyses are supported by exergy-based evaluation metrics. The Rational Exergy Management Efficiency of the hydrogen city model can reach 0.80, which is above the value of conventional district energy systems, and represents related advantages for CO 2 emission reductions. The option of incorporating low-enthalpy geothermal energy resources at about 80 • C to support the model is evaluated. The hydrogen city model is applied to a new settlement area with an expected 200,000 inhabitants to find that the proposed model can enable a nearly net-zero exergy district status. The results have implications for settlements using hydrogen energy towards meeting net-zero targets.
