“…It has been reported that Fe-based catalysts were efficient in tar removal during the biomass gasification, and the Fe/CaO catalysts have been used in biomass gasification-reforming reactions, aiming to produce hydrogen or synthesis gas [26,27]. Huang et al have investigated the effects of Fe/CaO catalysts on the biomass gasification in a fluidized bed reactor, and they found that the H 2 production yield was increased when Fe was loaded from 0% to 15% [27].…”

“…Huang et al have investigated the effects of Fe/CaO catalysts on the biomass gasification in a fluidized bed reactor, and they found that the H 2 production yield was increased when Fe was loaded from 0% to 15% [27]. So, in the fast pyrolysis of biomass reaction with Fe/CaO catalysts, a lower Fe load on the CaO support (5Fe/CaO) may be in favor of the increase of light and aromatic hydrocarbons, while larger Fe contents of the Fe/CaO catalysts (10Fe/CaO and 15Fe/CaO) might transform the light and aromatic hydrocarbons into small molecule gases, such as H 2 , CO and CO 2 , resulting in the decrease of yields of light and aromatic hydrocarbons.…”

“…Catalysts are well-known for their capability for accelerating biomass conversion through lowering activation energy, and for enhancing catalytic reforming to produce syngas [12,15,16]. For example, reduction of tar and significant increase in production of syngas have been achieved by adding olivine and alumina catalysts to biomass gasification using a conical spouted bed reactor [15].…”

“…Cheah et al [17] carried out biomass gasification using a nickel cerium olivine catalyst; they reported that the presence of catalyst resulted in a significant improvement of H 2 -enriched syngas production. In addition, the improvement of hydrogen production was reported by adding Fe/CaO catalyst to a continuous-feed fluidized bed reactor [16]. Supported noble metal catalysts such as Rh, Ru and Pt have been reported to effectively increase syngas yield [18][19][20][21].…”

Abstract:The production of hydrogen-enriched syngas from the thermo-chemical conversion of biomass was studied using Ni/CaAlO x catalysts prepared by coprecipitation method. The effect of Ca addition with different molar ratios of Ca:Al (1:3, 1:2, 1:1, 2:1, 3:1) on the properties and catalytic behaviour in relation to syngas production and the coke formation on the surface of the catalysts were investigated.Catalysts were characterized by BET, XRD, TPR, SEM, and TEM. The SEM and TEM results showed that rod-shaped nano-particles were highly dispersed on the surface of the catalyst. The particle size of NiO was slightly affected with the increase of Ca content in the catalyst. It appeared that the selectivity of CO was increased and the selectivity of CO 2 was reduced with the increase of Ca addition to the catalyst. For example, CO 2 concentration was reduced from 20 to 12 Vol.%, when the molar ratio of Ca/Al was increased from 1:3 to 3:1 for the Ni/CaAlO x catalyst; it is suggested that the water gas shift reaction was inhibited and CO 2 reforming reactions were promoted in the presence of the catalyst with higher Ca content. The CO/H 2 molar ratio could be manipulated by changing the Ca content in the catalyst, while the H 2 concentration remained almost constant (around 45 Vol.%). Thus, using the Ni/CaAlO x catalyst developed in this work could provide a promising route to control the syngas composition, which is an important factor for syngas applications.

“…Many types of catalysts such as alkali and alkali earth metal compounds [14][15][16], Fe [17], Rh [18], and Ru [19] supported catalysts have been investigated for biomass and plastic gasification. However, nickel based catalysts have been commonly used with steam as the hydrogen production catalyst.…”

Abstract:A Ni-Mg-Al-Ca catalyst was prepared by a co-precipitation method for hydrogen production from polymeric materials. The prepared catalyst was designed for both the steam cracking of hydrocarbons and for the in situ absorption of CO 2 via enhancement of the water-gas shift reaction. The influence of Ca content in the catalyst and catalyst calcination temperature in relation to the pyrolysis-gasification of a wood sawdust /polypropylene mixture was investigated.The highest hydrogen yield of 39.6 mol H 2 /g Ni with H 2 /CO ratio of 1.90 was obtained in the presence of the Ca containing catalyst of molar ratio Ni:Mg:Al:Ca = 1:1:1:4, calcined at 500 °C.In addition, thermogravimetric and morphology analyses of the reacted catalysts revealed that Ca introduction into the Ni-Mg-Al catalyst prevented the deposition of filamentous carbon on the catalyst surface. Furthermore, all metals were well dispersed in the catalyst after the pyrolysisgasification process with 20-30 nm of NiO sized particles observed after the gasification without significant aggregation.
