“…In most catalytic reactions, nano-catalysts have shown great advantages over bulk catalysts. For example in cracking of tar, an undesirable by-product in biomass conversion, Ni-Co/Si-P nanocatalysts succeeded in cracking 99% of the tar, which is a considerable improvement compared to 91% cracking from bulk catalyst of the same composition at catalytic bed temperature of 800 o C [154]. This improvement was attributed to several important features of the catalyst, such as particle size, surface area and porosity.…”

This review provides a comprehensive summary of current hydrocracking applications, and presents recent advances in the synthesis and structure/composition control of various nanomaterials used in hydrocracking catalysts. Although a wide range of feeds are considered in this review, particular focus is placed on hydrocracking of aromatic and paraffinic compounds.The significance, concepts and principles of the hydrocracking process are first discussed focusing on its wide range of industrial applications. Then, recent advances in the synthesis of hydrocracking catalysts are presented, including different types of zeolites and metal promoted catalysts. Finally, we compare the performances of a wide range of hydrocracking catalysts, and discuss how their intrinsic properties (e.g. surface area, porosity, acidity, morphology and structure) can be controlled to achieve optimal catalytic performance in hydrocracking of aromatic compounds, heavy petrochemicals, paraffinic hydrocarbons and vegetable oils.

“…Nickel-based catalysts are often used when hydrogen is the only product needed. Its activity is dependent on the presence or absence of the support material and other additives ( Kannaiyan et al, 2016 ). Table 3 shows the data related to a few recent reports about hydrogen production via direct biomass gasification method using Ni-based catalysts supported on various catalysts.…”

Thermocatalytic Hydrogen Production Through Decomposition of Methane-A Review

et al. 2021

Consumption of fossil fuels, especially in transport and energy-dependent sectors, has led to large greenhouse gas production. Hydrogen is an exciting energy source that can serve our energy purposes and decrease toxic waste production. Decomposition of methane yields hydrogen devoid of COx components, thereby aiding as an eco-friendly approach towards large-scale hydrogen production. This review article is focused on hydrogen production through thermocatalytic methane decomposition (TMD) for hydrogen production. The thermodynamics of this approach has been highlighted. Various methods of hydrogen production from fossil fuels and renewable resources were discussed. Methods including steam methane reforming, partial oxidation of methane, auto thermal reforming, direct biomass gasification, thermal water splitting, methane pyrolysis, aqueous reforming, and coal gasification have been reported in this article. A detailed overview of the different types of catalysts available, the reasons behind their deactivation, and their possible regeneration methods were discussed. Finally, we presented the challenges and future perspectives for hydrogen production via TMD. This review concluded that among all catalysts, nickel, ruthenium and platinum-based catalysts show the highest activity and catalytic efficiency and gave carbon-free hydrogen products during the TMD process. However, their rapid deactivation at high temperatures still needs the attention of the scientific community.

“…Catalyst regeneration is one of the possibilities to delay catalyst deactivation, but this trick can also lead to poor activity of catalyst and shorten its lifetime . For this reason, researchers tried to introduce various supports to enhance catalytic activity and sustainability of Ni‐based catalysts . The strong Ni‐support interaction makes the catalysts highly resistant to sintering and deactivation.…”

“…Kannaiyan et al studied the catalytic performance of a Ni‐Co/Si‐P catalyst, which was prepared by a deposition‐precipitation method in biomass gasification. The authors concluded that experimentation with Ni‐Co/Si‐P catalyst can result in tar cracking of 99.0 % as compared to 91.5 % from the bulk mode.…”

Experimental Study on Catalytic Biomass Gasification in a Bubbling Fluidized Bed

2018

A bubbling fluidized‐bed gasification system was selected for catalytic steam gasification of rice straw with four Ni‐based catalysts, i.e., Ni/Al2O3, Ni/CeO2, Ni/MnO2, and Ni/MgO. The effect of temperature, steam/biomass ratio (S/B), and catalyst/biomass ratio (C/B) on the gas composition, char conversion, and hydrogen yield was evaluated. It was found that higher temperature and S/B promote hydrogen production and char conversion. The results also demonstrated that the catalytic activity of Ni/Al2O3 under different S/B values is better than those of the other catalysts. Regarding the catalyst activity, all four catalysts exhibited good performance in terms of tar removal and carbon conversion. However, the performance of Ni/Al2O3 was superior to that of the other three catalysts.
