“…As a matter of fact CO can be only generated during calcination by reaction of carbon with CO 2 in Boudouard's equilibrium. As a consequence, as already verified in literature [24], the presence of CO can partly justify the observed decay in catalyst efficiency. The use of a higher steam to carbon ratio could solve this problem.…”

“…Results show high efficiency during the first cycle (81.3% on average), followed by expected lower values (as already perceived in Figure 3). Hence its trend confirms the dolomite progressive loss of sorption capacity during cycles, often accompanied with structural modification, pore volume and surface area reduction, as widely reported in literature [13,24]. Table 7 also reports the total amount of CO detected within the gas stream during the calcination phase.…”

“…The greatest efforts are directed to the synthesis of tailored binders or support for CaO to enhance its reactivity and stability. Di Felice et al [29,30], for example, have reported successful results in single cycle CO 2 capture and TAR reduction with dolomite impregnated by nickel or iron, using toluene and 1-methyl naphthalene as model compound for TAR produced during biomass gasification and in multi-cycle Sorption Enhanced Steam Methane Reforming too [24].…”

“…Therefore, combining catalytic reforming and CO 2 absorption through contemporary use of CaO sorbent and catalyst as bed material in fluidised bed reactors (in a process called Sorption Enhanced Steam Reforming-SESR) it is possible to obtain the best result in H 2 -rich syngas production [24].…”

Abstract:The aim of this work was the evaluation of the catalytic steam reforming of a gaseous fuel obtained by steam biomass gasification to convert topping atmosphere residue (TAR) and CH 4 and to produce pure H 2 by means of a CO 2 sorbent. This experimental work deals with the demonstration of the practical feasibility of such concepts, using a real woodgas obtained from fluidized bed steam gasification of hazelnut shells. This study evaluates the use of a commercial Ni catalyst and calcined dolomite (CaO/MgO). The bed material simultaneously acts as reforming catalyst and CO 2 sorbent. The experimental investigations have been carried out in a fixed bed micro-reactor rig using a slipstream from the gasifier to evaluate gas cleaning and upgrading options. The reforming/sorption tests were carried out at 650 °C while regeneration of the sorbent was carried out at 850 °C in a nitrogen environment. Both combinations of catalyst and sorbent are very effective in TAR and CH 4 removal, with conversions near 100%, while the simultaneous CO 2 sorption effectively enhances the water gas shift reaction producing a gas with a hydrogen volume fraction of over 90%. Multicycle tests of reforming/CO 2 capture and regeneration were performed to verify the stability of the catalysts and sorbents to remove TAR and capture CO 2 during the duty cycle.

“…The contaminants are usually removed by filtration and catalytic conditioning [15]. The reforming of light hydrocarbons and tars [16][17][18][19][20][21][22] as well as the water gas shift to control the CO to H 2 ratio [23] are the most used processes for the upgrading of the gas.…”

Deactivation of a Ni-Based Reforming Catalyst During the Upgrading of the Producer Gas, from Simulated to Real Conditions

et al. 2011

View full text Add to dashboard Cite

The deactivation of a nickel reforming catalyst during the upgrading of the producer gas obtained by gasification of lignocellulosic biomass was studied. The research involved several steps: the selective deactivation of the catalyst in a laboratory scale; the streaming of the catalyst with the producer gas of a downdraft and an oxygen/steam circulating fluidized bed (CFB) gasifier; and tests in a reformer placed in a slipstream of the CFB gasifier. The information obtained allowed to elucidate the catalyst deactivation mechanisms taking place during the reforming of the producer gas: physical deactivation by deposition of fine ashes, aerosol particulate or carbon; poisoning by H 2 S and HCl present in the gas phase and thermal sintering because of the high operation temperatures required to avoid the chemical deactivation. These physical and chemical effects depended on the composition of the biomass fuel.
