This research looks at the potential of utilizing microplastics waste (MPW) found in oceans and soil as a source of liquid fuel. A significant portion of this pollutant is presently untreated and ends up in landfills, exacerbating the worldwide issue of marine and land pollution. Pyrolysis is a tertiary recycling process that is presented as a solu...

Global population growth and accelerated urbanisation have resulted in massive amounts of fossil fuel use and waste production. Because of its high energy content, pure nature, and fuel quality, hydrogen fuel is a viable option to fossil fuels. Biohydrogen from agricultural waste, in particular, piques concern because it generates hydrogen while st...

This research investigates the preparation of Ni-Co/CeO2 catalysts based on impregnation and hydrothermal treatment methods for the hydrogen and valuable fuels generation from the steam reforming and cracking reactions of polyethylene terephthalate (PET) waste liquefied in phenol. PET plastic waste is environmentally harmful, mostly when it elimina...

As a sustainable and renewable energy carrier for transition, hydrogen is considered as a key future fuel for the low carbon energy systems. During the past few decades, attention has been given to the conversion of waste materials, including plastics to the production of hydrogen. Studies in this field are of great importance because they resolve...

The recycling of plastic waste is a good idea for countries which concern air pollution, CO2 emission, and public health. In this research article, PET, as one of the significant plastic waste, was selected to dissolve in phenol for value‐added liquid fuels and hydrogen gas production. This research aims to provide insight into the mechanism of PET...

Ni–Co/ZrO2 (NCZ) nano-structure catalysts prepared by the hydrothermal method (NCZ-hyd) and conventional impregnation (NCZ-imp) method. The comparative catalytic activity and coke resistance for each prepared catalyst were examined in steam reforming of phenol and polyethylene terephthalate (PET) plastic waste.

Dendrimeric fibrous silica HZSM-5 (HFSZ) catalysts were prepared using a microemulsion technique and ZSM-5-seeding crystallization with different oil phases, benzene, toluene, and xylene, and denoted as FB, FT, and FX, respectively. The HFSZ catalysts possessed a well ordered crystalline structure with chestnut-like spherical particles, rich with d...

High-octane gasoline production by catalytic naphtha reforming is a major process in the petroleum industry. Sulfur components involved in the reforming process are causing pollutions and catalyst poisoning. Hydrodesulfurization has been developed to remove sulfur species from naphtha. Bimetallic and trimetallic catalysts are used to improve the na...

The effect of different pellet sizes of nickel (Ni) and lanthanum (La) promoted Al2O3 support on the catalytic performance for selective hydrogen production from polyethylene terephthalate (PET) plastic waste via steam reforming process has been investigated. The catalysts were prepared by impregnation method and were characterized using XRD, BET,...

Production of hydrogen from plastic waste could be a prospective key to the ecological problems resulted from waste. To further explore the process, a 32-runs parametric study on the steam reforming of Polyethylene terephthalate (PET) dissolved in phenol was conducted in a fixed bed reactor using Ni over La2O3-Al2O3 support. The five factors studie...

Tremendous research efforts have been dedicated towards development and utilization of sustainable alternative energy resources. Depletion of fossil fuels and the rising environmental concerns such as global warming are among the reasons that necessitated such. Hydrogen (H2) has been widely considered a clean fuel for the future, with the highest m...
