Modern Methods of Obtaining Synthetic Oil from Unconventional Hydrocarbon Raw Materials: Technologies, Catalysts, and Development Prospects

Polymers, Journal Year: 2025, Volume and Issue: 17(6), P. 776 - 776

Published: March 14, 2025

This article considers modern approaches to obtaining synthetic oil from unconventional hydrocarbon feedstocks, including plastic waste, tires, biomass, coal, and extra-heavy oil. Particular attention is paid multi-stage technologies, such as pyrolysis, catalytic depolymerization, gasification followed by Fischer–Tropsch synthesis, hydrocracking of heavy residues. The important role catalysts in increasing the selectivity economic efficiency processes noted: nanostructured, bifunctional, pollution-resistant systems are increasingly used. Economic factors influencing competitiveness this industry considered, volatility prices for traditional oil, government support measures, development waste logistics infrastructure. It emphasized that strengthening position associated with growth environmental requirements stimulating recycling plastics, biomass; at same time, compliance high standards transparency emission control play a critical social aspects projects. In addition improving situation, contributes creation jobs, resolution problems shortage classical fields, increase energy security. concluded further improvement technologies integration into industrial clusters can turn sphere significant component future sector.

Synthesis of Ecofriendly Bimetallic Pt/Ni Nanoparticles on KNbO3 via Hydrothermal Process for Sustainable Hydrogen Evolution from NaBH4

Processes, Journal Year: 2024, Volume and Issue: 12(11), P. 2340 - 2340

Published: Oct. 24, 2024

The performance of nickel and platinum bimetallic nanoparticles (NPs) supported on potassium niobate (KNbO3) is evaluated in the catalytic hydrolysis sodium borohydride (NaBH4) to generate hydrogen (H2). KNbO3 was synthesized via a hydrothermal route using Nb2O5 KOH as precursors. X-ray diffraction (XRD) confirmed crystalline orthorhombic structure KNbO3. Ni/Pt NPs, with an average size 4.66 nm spherical morphology, were uniformly dispersed surface nanosheets. N2 physisorption isotherms NPs classified type V H3 hysteresis, showing specific areas 0.170 2.87 m2 g−1, respectively. Catalytic studies examined various molar ratios, 1:3 ratio (mol/mol) demonstrating highest efficiency. Kinetic analysis NaBH4 showed that data fit pseudo-first-order model. An increase temperature enhanced generation rate (HGR), reaching 2068.3 mL gcat−1 min−1 at 315.05 K. apparent activation energy (Ea) determined be 29.9 kJ mol−1. Durability assays only 11% decrease activity after 11 cycles. Thus, promising, easy-to-synthesize, environmentally friendly catalyst for has been developed.
