“…The catalytic performance of each Ni/spinel catalyst was evaluated by using the same system at reaction temperatures of 700, 800, and 900 °C. Previous studies were consulted to determine these operating conditions . The concentrations of H 2 , CH 4 , CO, and CO 2 at the inlet and outlet of the reactor were determined by using an online gas analyzer (JUSUN, AGM 4000).…”

Enrichment of Hydrogen Production from Biomass‐Gasification‐Derived Syngas over Spinel‐Type Aluminate‐Supported Nickel Catalysts

Synthesis gas produced through biomass gasification can be converted into H2‐rich gas by catalytic methane decomposition or reforming reactions. In this study, we investigate the promotion of hydrogen production by the catalytic reforming of a model biomass‐gasification‐derived syngas over Ni/MAl2O4 (M=Mg, Ni, and Ca) catalysts. Three mesoporous spinel supports were synthesized by solution combustion. Ni/NiAl2O4 and Ni/CaAl2O4 exhibited better catalytic activities and stabilities for syngas reforming than the other catalysts. These results are ascribable to interactions between the metallic catalyst and spinel supports, and stronger interactions lead to smaller catalyst particles. The formation of coke deposits is associated with CH4 decomposition during the syngas reforming reaction. Clearly, H2 production is lower at 900 °C because of increased competition from the reverse water–gas shift reaction that shifts the reaction between CO2 and H2 toward the generation of CO and H2O.

“…As the primary product of gasification, syngas is a mixture of product gases mainly consisting of carbon monoxide (CO), hydrogen (H2), carbon dioxide (CO2), and methane (CH4), which can be catalytically converted into liquid fuel (i.e., Fischer-Tropsch), value-added chemicals (e.g., ammonia, methanol), or directly used as a fuel for power generation (Asthana et al, 2017;Lee et al, 2017b;Wang et al, 2017). The H2 production from the gasification of biomass has received particular interest because of its relatively high efficiency (>50%) and eco-friendly nature (Hosseinpour et al, 2017;Moneti et al, 2016;Parthasarathy & Narayanan, 2014;Yao et al, 2016). Moreover, the cost of the H2 production from biomass gasification was 4 $14 -25 /GJ, which was lower than that from wind-, solar-, and nuclear-based methods (Balat & Kırtay, 2010).…”

Syngas and biochar production are mainly influenced by temperature, feedstock properties, gasifying agent, pressure, and the mass ratio between gasifying agent and feedstock with temperature being the most significant factor. Increasing temperature generally promotes syngas production while suppressing biochar production. The selection of gasifiers (fixed bed, fluidized bed, and entrained flow) is highly dependent on scale requirement (e.g., volume of feedstock and energy demand), feedstock characteristics (e.g., moisture and ash content), and the quality of syngas and biochar. Updraft fixed bed gasifiers are suitable for the feedstocks with a moisture content up to 50 wt.%. High ash feedstocks such as Indian coal, dried sewage sludge, and municipal solid waste that are not suitable for fixed bed gasifiers, have been successfully gasified in bubbling fluidized bed reactors. Woody biomass is not suitable for entrained flow gasifiers unless specialized feeding methods are employed such as wood torrefaction and grinding followed by the existing feeding methods for pulverized coals, biomass-oil biochar slurry preparation followed by pumping, wood or torrefied wood slurry preparation followed by pumping, etc. Syngas and biochar can potentially be contaminated by NH3, H2S, and tar, which can be removed using catalysts (e.g., Ni-based), metal oxides-based sorbents, and thermal and catalytic cracking methods. Existing syngas and biochar upgrading methods suffered from various problems such as economic infeasibility, limited productivity, and fouling, and future syngas and biochar upgrading methods should be aimed to have the features of reliability, security, affordability, and sustainability, towards the practical, largescale production of syngas-and biochar-based products. One potential solution is to develop integrated systems by combining biochar upgrading and application with syngas upgrading, which warrants an integrated perspective based on both life cycle assessment and economic analysis.

“…Last but not least, gasification also produces valuable solid products such as biochar and ash at the end of the process [15,16] which have a great application potential in multiple fields including building and construction, agriculture, water treatment, catalysis and etc. [17][18][19]. For example, biochar can be mixed into soil for agricultural purposes to enhance soil quality and nutrient content [20,21].…”

The management and disposal of livestock manure has become one of the top environmental issues at a global scale in line with the tremendous growth of poultry industry over the past decades. In this work, a potential alternative method for the disposal of chicken manure from Singapore local hen layer farms was studied. Gasification was proposed as the green technology to convert chicken manure into clean energy. Through gasification experiments in a 10 kW fixed bed downdraft gasifier, it was found that chicken manure was indeed a compatible feedstock for gasification in the presence of wood waste. The co-gasification of 30 wt% chicken manure and 70 wt% wood waste produced syngas of comparable quality to that of gasification of pure wood waste, with a syngas lower heating value (LHV) of 5.23 MJ/Nm 3 and 4.68 MJ/Nm 3 , respectively. Furthermore, the capability of the gasification derived biochar in the removal of an emerging contaminant (artificial sweetener such as Acesulfame, Saccharin and Cyclamate) via adsorption was also conducted in the second part of this study. The results showed that the biochar was effective in the removal of the contaminant and the mechanism of adsorption of artificial sweetener by biochar was postulated to be likely via electrostatic interaction as well as specific interaction. Finally, we conducted a cost-benefit analysis for the deployment of a gasification system in a hen layer farm using a Monte Carlo simulation model.
