Catalytic pyrolysis oil (CPO) was produced from lignin using the ex-situ mechanism and nanoporous HZSM-5 (SiO2/Al2O3 = 50) as a catalyst. The oil contained phenolics, esters, acids, and benzene derivatives as the major constituents. The emulsification of CPO in diesel was tested with several emulsifier combinations such as Span 80 and Tween 60, Span 80 and Atlox 4916, and Atlox 4916 and Zephrym PD3315 in the HLB range of 5.8–7.3. The HLB value of 5.8 using the combination of Span 80 and Atlox 4916 and the CPO:emulsifier:diesel ratio of 5:2:93 (wt%), provided a stable emulsion for 10 days. The physiochemical properties of that emulsion were comparable to diesel. Hence, emulsions of CPO and diesel can potentially be used as a diesel engine fuel.

Effects of sorbitol derivative surfactants on the stability of pyrolysis oil emulsion prepared from plastic waste were experimentally investigated. The water-pyrolysis oil mixture emulsified by Sorbitan monooleate (Span 80) surfactant is more stable than the water-in-oil emulsions prepared by other Sorbitol derivative surfactants which have lower hydrophilic-lipophilic balance (HLB) numbers. The Span 80 concentration of 1.5% by volume was found to produce the most stable emulsion and the smallest average water droplet. This optimal surfactant concentration is the same as critical micelle concentration.

Utilising pyrolysis as a waste tyre processing technology has various economic and social advantages, along with the fact that it is an effective conversion method. Despite extensive research and a notable likelihood of success, this technology has not yet seen implementation in industrial and commercial settings. In this review, over 100 recent publications are reviewed and summarised to give attention to the current state of global tyre waste management, pyrolysis technology, and plastic waste conversion into liquid fuel. The study also investigated the suitability of pyrolysis oil for use in diesel engines and provided the results on diesel engine performance and emission characteristics. Most studies show that discarded tyres can yield 40–60% liquid oil with a calorific value of more than 40 MJ/kg, indicating that they are appropriate for direct use as boiler and furnace fuel. It has a low cetane index, as well as high viscosity, density, and aromatic content. According to diesel engine performance and emission studies, the power output and combustion efficiency of tyre pyrolysis oil are equivalent to diesel fuel, but engine emissions (NOX, CO, CO, SOX, and HC) are significantly greater in most circumstances. These findings indicate that tyre pyrolysis oil is not suitable for direct use in commercial automobile engines, but it can be utilised as a fuel additive or combined with other fuels.
