“…Upon evaluation of the results at the studied temperatures, we can infer that the increase in conversion observed for all feedstock at 420 °C (Figure 1b) also translates into increased LPG formation (Figure 2b), likely because of the further cracking of the degraded polymer chains, particularly for the PMMA/VGO blend (with selectivity values of 20.7 % and 28.5 % at 400 ºC and 420 °C, respectively). At higher temperatures, the dry gas selectivity of VGO and PMMA/VGO is intensified due to the thermal cracking activity [36].…”

“…In the past few decades, there has been consistent advancement in FCC technology. This process breaks down the larger hydrocarbon molecules into smaller ones and producing valuable products (Miao et al, 2021;Otten-Weinschenker and Mönnigmann, 2022). The FCC has three main reactors, namely the riser, stripper, and regenerator, with the riser being the primary reactor where the catalytic cracking reaction occurs (Selalame et al, 2023).…”

Fluid catalytic cracking could convert crude palm oil into valuable green fuels to substitute fossil fuels. This study aimed to predict the phenomenon and green fuels yield in the industrial fluid catalytic cracking riser using computational fluid dynamics. A three-dimensional transient simulation using the Eulerian-Lagrangian with the multiphase particle-in-cell is to investigate reactive gas-particle hydrodynamics and the four-lump kinetic network model with the rare earth-Y catalyst for crude palm oil cracking behaviors. The study results show that the fluid and catalyst velocity profile increase in the middle of the riser reactor because the cracking reaction process that produces OLP and Gas products has a lighter molecular weight. The endothermic reaction causes the temperature profile to decrease because the heat of the reaction comes from the catalyst. This analysis shows that the simulation accurately predicts green fuel products from crude palm oil. As a result, the crude palm oil conversion, organic liquid product yield, and Gas yield correspond to 70 wt%, 28.8 wt%, and 27.5 wt%, respectively. Compared to the experimental study, the computational prediction of yield products showed good agreement and determined the optimal riser dimension. The methodology and results are guidelines for optimizing the FCC riser process using CPO.

“…[4] Methods of industrial hydrogen production include catalytic cracking and electrolysis of water. [5][6] However, these methods have some disadvantages; for example, the consume a high amount of energy, generate pollutants, and use nonrenewable energy resources. These disadvantages have hindered the development of large-scale application of hydrogen.…”

Using natural biomass as sacrificial agent for photocatalytic hydrogen production is a current topic of interest in the field of new energy research because it has widely available resources, is economical, and has environmental benefits. In this study, we propose a strategy for photocatalytic hydrogen production using acid-treated corn straw and its extracts as a sacrificial agent. Furthermore, the important factors that affect the photocatalytic performance of hydrogen production are also studied. X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), and scanning electron microscopy (SEM) are employed to characterize the composition, structure, and morphology of the corn straw. High-performance liquid chromatography (HPLC) is employed to characterize the composition of extracts in the filtrate obtained from acid treatment. The results from the above analyses show that cellobiose and xylose, which are extracted from corn straw, significantly improve the hydrogen production performance. The optimal hydrogen generation rates in this study reach 30.583 μmol/h in 100 mL of water; this is 72 times greater than that using pure water, 2 times greater than that using raw corn straw, and 4.5 times greater than that using acid-treated corn straw. Also, from these characterizations and analyses, the possible photocatalytic mechanism of this system is also proposed in this paper.
