The Haber-Bosch process for NH3 production is one of the largest global energy consumers. Despite improvements over past century, developing catalysts with enhanced activities and durabilities remains challenging. Ru-based supported on CeO2 are suitable alternatives under mild reaction conditions. Here, we elucidated effects Ru structure physicochemical properties catalytic Ru-CeO2 systems. One-pot syntheses metal–organic frameworks as sacrificial templates were used to prepare single-atom,...
Various heavy oil feedstocks were investigated using several methods that are commonly employed to evaluate the stabilities of such feedstocks. More specifically, microcarbon residue (MCR) content, colloidal instability index (CII), stability (SI), and Heithaus parameter (P value) employed. The catalytic hydrocracking oils was carried out in a slurry-phase semi-batch reactor at 410 °C under 110 bar hydrogen presence Mo-octoate precursor (1000 wppm). correlation between feedstock properties...
The surge in global plastic production, reaching 400.3 million tons 2022, has exacerbated environmental pollution, with only 11% of being recycled. Catalytic recycling, particularly through hydrogenolysis and hydrocracking, offers a promising avenue for upcycling polyolefin plastic, comprising 55% waste. This study investigates the influence water on depolymerization using Ru catalysts, revealing promotional effect when both metal acid sites, Brønsted site, are present. Findings highlight...
Nickel and iron compounds have garnered attention as catalysts for upgrading heavy oil via aquathermolysis. However, research on the performance of bimetallic oxide in aquathermolysis remains limited. To that end, NiO–Fe2O3 were prepared this study using a simple physical mixing method employed heavy-oil to investigate synergistic relationship between NiO Fe2O3. The product distributions quality systematically analyzed, an asphaltene index was introduced evaluate coke-inhibiting ability...
Abstract Depolymerizing plastic waste through hydrogen‐based processes, such as hydrogenolysis and hydrocracking, presents a promising solution for converting plastics into liquid fuels. However, conventional hydrogen production methods rely heavily on fossil fuels, exacerbating global warming. This study introduces novel approach to that utilizes in situ generated via the aqueous phase reforming (APR) of methanol, biomass‐derived chemical offering more sustainable alternative. Our results...

Environmental problems are worsening due to the complexity in managing plastic waste. Chemical recycling emerges as a pivotal technology that can suppress carbon introduction into cycle and provide petroleum alternatives for current petrochemical processes. The utilization of zeolites reduce energy consumption by lowering operation temperature pyrolysis. Here, we demonstrate low-temperature catalytic cracking polyethylene (PE) utilizing an open-batch reactor configuration *BEA-type zeolite...
