Special Issue Information

Dear Colleagues,

There is a global imperative on waste valorization to reduce reliance upon fossil fuels and, at the same time, to recovery the energy and material values from wastes. The thermochemical conversion technology, pyrolysis, converts biomass waste into fuels and chemicals in gaseous, liquid and solid forms. However, noncatalytic pyrolysis suffers from the low quality of the products; for example, pyrolysis oil cannot be directly used in engines due to its complexity and instability. Catalytic pyrolysis was proposed to ensure the efficient generation of pyrolysis products whilst maximizing the value of biomass into fuels and value-added chemicals in the presence of catalysts.

This Special Issue aims to cover the most recent progress and the advances in the field of catalytic pyrolysis. This includes, but is not limited to, catalytic pyrolysis processes; catalytic reactors; the mechanism and kinetics of catalytic pyrolysis; the synthesis, characterization and evaluation of advanced catalysts (zeolites, metal oxides, bimetallics, dolomite, etc). Any original research and review articles dealing with experimental or modelling work related to catalytic pyrolysis are welcome.

The increasing global population and the rapid industrial development associated therewith have increased the demand for fossil-derived fuel oils. The sources of fossil fuels are limited, and many studies have been being conducted to find alternative fuel sources. Waste tire pyrolysis oil (WTPO) attracts considerable attention as an alternative fuel because its properties are similar to those of diesel oil. However, WTPO has a high sulfur content of >1.0 wt%, which is above the environmental standard limit of 0.1 wt%; therefore, it cannot be used in engines directly. It is thus highly necessary to remove sulfur compounds from tire-derived oils. However, finding an appropriate and environmentally friendly process is proving difficult. This review article presents the various desulfurization methods used to removal sulfur from WTPO, such as hydrodesulfurization (HDS), oxidative desulfurization (ODS), ultrasound-assisted oxidative desulfurization (UAOD), and acid treatment. Of these, HDS is the most expensive as it involves high consumption of hydrogen, high temperature (~450 °C), and high pressure (~200 bar), whereas UAOD is an efficient and economic method of reducing the sulfur content of WTPO.
