Catalytic steam reforming of simulated bio-oil for green hydrogen production using highly active LaNi_xCo_1−xO₃ perovskite catalysts

Abstract

Catalytic steam reforming (SR) of agricultural waste derived bio-oil for hydrogen production is a unique technology, offering twin benefits of waste management as well as sustainable energy production. In the...

From Waste to Clean Energy: An Integrated Pyrolysis and Catalytic Steam Reforming Process for Green Hydrogen Production from Agricultural Crop Residues

“…As discussed above in the FESEM analysis of the spent catalyst, coke deposited can generally be classified into two categories: amorphous or encapsulating and filamentous or graphitic . In recent years, TG analysis has been extensively utilized to investigate and quantify the amount of coke formed, ,,,, with the results suggesting that that the deposited species undergo oxidation temperatures between 300 and 700 °C. Here, the temperature of oxidation is influenced by the nature of coke, with the consensus being that amorphous coke undergoes oxidation at temperatures below 450 °C while filamentous coke undergoes combustion at temperatures greater than 450 °C .…”

“…63 Here, as displayed in Figure 11, the major weight loss was noted between 400 and 700 °C, signaling that the coke deposited was majorly graphitic or filamentous in nature, which is in good agreement with both the results of the spent catalyst's FESEM and Raman analysis in this study as well as our previous studies. 26,28 Furthermore, the coke deposition rate was also computed and found to be 24.1 mg g cat −1 h −1 .…”

“…To address these challenges, recent studies have increasingly focused on enhancing the efficiency of Nibased catalysts through the exploration of innovative catalytic materials such as spinels, perovskites, etc. 20,25 Perovskite-type metal oxides, characterized by the general formula ABO 3 , have emerged as a promising class of catalysts for H 2 production via reforming, demonstrating exceptional performance with both methane 38 and simulated bio-oil 26,28 as feedstocks. The A sites in perovskites can be occupied by both lanthanide/rare-earth and alkaline earth metals.…”

“…Alternative fuels for instance biofuels, biodiesel, and hydrogen (H 2 ) are trending among researchers to fulfill this demand. With the advancement in hydrogen production and storage, such as fuel cells, it has become one of the best alternatives for fossil fuels owing to its highest calorific value and zero carbon emission during combustion. , However, one of the biggest perils of hydrogen fuel is the self-combustion of H 2 even at a low concentration (above 4%) in the atmosphere . This leads to an increased risk of explosions and danger to mankind.…”
