“…However, the high concentration of Cu impregnation may also inhibit the catalytic pyrolysis reaction under high-temperature conditions because the high relative acid active sites cracked the long residue fraction into smaller hydrocarbon compounds and further attributed the secondary cracking reaction to a slight increase in the gaseous product yield. Moreover, excessive Cu-impregnated sFCC showed a lower content of both kerosene-like and diesel-like fractions because copper inhibited the catalytic activity in the microporous structure, resulting in the middle volatile hydrocarbon compounds from thermal degradation not successively passing through the textural structure of the parent catalyst and having difficulty reacting with the acidic active site. − ,− , Therefore, the product yield distribution of desirable products in both kerosene- and diesel-like fractions tended to decrease. It is obvious that the selectivity of diesel-like on all series of Cu-modified sFCC represented higher selectivity than that from the parent sFCC.…”

“…Furthermore, increasing the process temperature can enhance the catalytic pyrolysis of SLO/LDPE and decompose large hydrocarbon molecules into smaller hydrocarbons. Then, the catalytic reaction enhances the scission of middle compounds, promotes the hydrogen transfer reaction over the acidic active site of Cu-sFCC, and enhances the β-scission of middle compounds into a small linear alkane. − , As shown in Figure , the product distribution of the catalytic pyrolysis of SLO/LDPE over Cu-sFCC obtained at 400 °C consisted mainly of a long residue fraction of 42.91 wt %, while the proportions of diesel-like, kerosene-like, and naphtha-like residues were 13.74, 8.38, and 5.63 wt %, respectively. It seems that a low operating temperature was not enough to accelerate the thermal decomposition of large hydrocarbon molecules, especially from SLO, and could not enhance the catalytic activity of the copyrolysis of SLO/LDPE because large hydrocarbon compounds could not arrange into middle hydrocarbon compounds by thermal degradation.…”

“…However, one major limitation of microporous catalysts is often limiting the catalytic activity and further catalytic efficiency for a large hydrocarbon compound according to intracrystalline diffusion, resulting in obstacles to the cracking reaction, isomerization, and arrangement of large hydrocarbon molecules into smaller hydrocarbon compounds at similar fractions to naphtha kerosene or diesel. − , Consequently, the modification of zeolite with metal doping has attracted much attention to improving both the acid strength and catalytic activity of the cracking reaction, − which might favor a higher yield of shortened hydrocarbon compounds that also effectively improve the catalytic oil to meet the stringent standard properties for diesel-like products in commercialized transport fuels. ,,,− Therefore, plastic waste entails dumping it at landfills, which can lead to numerous environmental pollution. The disposal of spent lubricant oil is collected and burned to produce heat energy, whose potential can be converted into energy by thermochemical reaction.…”

This work provided catalytic copyrolysis of spent lubricating oil (SLO) with waste low-density polyethylene (LDPE) using copper modification of a spent fluid catalytic cracking (sFCC) catalyst to produce diesel-like fuels in a microbatch reactor, which will lead to effective waste management, ensure sustainability, and serve as an alternative energy source. The effects of LDPE blended with SLO, temperature, reaction time, and catalyst loading using an inert nitrogen atmosphere were investigated on the yields and distributions of copyrolyzed oil, while metal modification of the sFCC was prepared and used to investigate the catalytic activity. The temperature and time of reaction played an important role in the gaseous contribution to the pyrolysis of SLO. The addition of the LDPE ratio in the catalytic copyrolysis, including Cu loading on a spent FCC template, also enhanced the acidity and was responsible for the catalytic activity, which could improve the product distribution and chemical compounds in a range of diesel-like fuels. It was shown that the pyrolyzed oil was in the range of C7–C26 with a maximum diesel-like fraction of 23.11 ± 2.88 wt % compared with the catalytic pyrolysis of SLO alone, which contained a diesel-like fraction of only 12.45 ± 1.92 wt %. It was noticed that the acid active site of the catalyst resulted in a carbon–carbon bond cleavage and further secondary reaction, leading to the conversion of the long residue fraction into a light oil product. In addition, the LDPE ratio in the catalytic copyrolysis could improve the product distribution and chemical compounds in a range of diesel-like compounds, as confirmed by the GC/MS analysis. Catalytic copyrolysis oil of the optimal process condition (0.7:0.3 mass molar of SLO/LDPE, 450 °C, 60 min, 3 wt % Cu-sFCC, and 10 wt % catalyst loading) mainly contains light hydrocarbons in the C7–C19 range. Accordingly, both the product selectivity and the conversion of the long residue to the diesel-like fraction were nearly stable (59.01 ± 1.36%) during the catalyst reusability test from one to three cycles without regeneration and significantly decreased after the fifth cycle. This is an indication that the copyrolysis enhanced the conversion of SLO by LPDE blended into smaller hydrocarbon compounds, and the catalytic activity therefore showed a major tendency toward the formation of diesel-like fractions (C8–C18).

Bioenergy possesses the potential to alleviate our energy demands while maintaining renewability and carbon neutrality. The utilization of abundant biomass sources for bioenergy production presents a significant challenge. When considering chemical processes for conversion, the development of effective catalysts becomes imperative as they play a pivotal role in biomass-to-bioenergy/biofuel conversion. In such scenarios, heterogeneous nanoporous materials emerge as crucial components for facilitating catalytic conversion. This perspective provides a comprehensive summary of biomass, including its classification, valorization processes and applications along with recent advancements in various catalytic systems utilized for transforming biomass and its intermediates into renewable energy products. We delved into the diverse classes of heterogeneous catalysts, including metal-based, metal oxide-based, silica based, hybrid catalysts, and organic polymers, highlighting their unique structural and compositional features that influence catalytic activity and selectivity. Furthermore, we discussed the importance of pore structure, surface area, and active site accessibility in enhancing catalytic performance. By examining the advantages and limitations of different catalysts, we provide insights into the rational design and optimization of porous heterogeneous catalysts for efficient and sustainable bioenergy conversion. This perspective serves as a valuable resource for researchers and engineers in the field of renewable energy, seeking to develop innovative catalyst materials for biomass valorization.

Since plastic and food waste are both types of non-lignocellulosic biomass, these must be handled and managed correctly to avoid pollution problems and damage to the environment. Bio-oil, made from recycled materials, including plastic and food waste, is one focus of these attempts. The co-pyrolysis method is being investigated in this study as a technique of recycling plastic waste and food waste to produce biofuels with reduced environmental impact. In terms of energy efficiency, bio-oil is unequal to other fuels like coal or natural gas because of its high acidity, high oxygen content, and low thermal stability. Therefore, a vacuum distillation process is required to improve bio-oil quality by adjusting the distillation temperature from 300 to 350 OC and the percentage of plastic waste used from 30 to 50%. The bio-oil was analyzed using a Gas Chromatography-Mass Spectrometer (GC-MS). The general compound showed that acids (60%) and alcohols (20%) were the most prevalent chemical compounds, followed by phenol (4%), aldehyde (14%), aliphatic (5%), Furan (14%), and ketones (11%) at maximum temperature (350 oC) for 30-50% plastic waste. Meanwhile, the final product is affected by temperature and plastic waste (PET) ratio factors. At 350 °C and a plastic waste addition of 50%, the highest bio-oil yield is 45%.
