MgO modification effectively suppressed strong Brønsted acid sites, leading to enhanced para-selectivity by inhibiting disproportionation, isomerization, and deep alkylation reactions. The introduction of palladium provided hydrogenation–dehydrogenation functionality, markedly improving catalyst stability by suppressing olefin oligomerization and coke formation. As a result, high selectivity toward p-ethyltoluene was achieved at moderate toluene conversion under optimized conditions. The influence of reaction temperature, space velocity, and toluene/DEC molar ratio on catalytic performance was systematically investigated. Toluene conversion exhibited non-monotonic behavior with respect to these parameters, reflecting a balance between DEC activation, reactant contact time, and catalyst deactivation. Optimal operating conditions provided high para-selectivity while limiting secondary isomerization and polyalkylation reactions. Fresh and spent catalysts were characterized by XRD, N2 physisorption, NH3-TPD, Py-IR, TEM, TGA, and DSC. These analyses revealed that MgO modification alone leads to the formation of condensed, pore-blocking coke, whereas palladium alters the nature of carbonaceous deposits toward less condensed species, thereby enhancing catalyst stability. Compared with literature systems based on alcohols and other carbonates, the developed catalysts operate at lower alkylating-agent excess and higher space velocities while maintaining competitive conversion and para-selectivity.","PeriodicalId":725,"journal":{"name":"Petroleum Chemistry","volume":"66 1","pages":"28 - 48"},"PeriodicalIF":1.1,"publicationDate":"2026-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147559083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The findings demonstrate the critical importance of reaction kinetics in determining the actual product distribution, particularly given the extended time required for reach equilibrium under these conditions. The influence of kinetics was evaluated across a pressure range of 1 to 100 bar. Although near-complete O2 conversion (>99.99%) is achieved very rapidly at high pressures, a significant amount of unreacted methane remains at this point. Attaining high methane conversion in the post-flame zone requires a time frame that is several orders of magnitude longer. This is attributed to the increasing impact of the partial pressure of H2 produced in this zone, which shifts the equilibrium in the reaction system (2CH4 ↔ C2H4 + 2H2 ↔ C2H2 + 3H2) to the left. This shift, in turn, reduces both the acetylene content in the gas mixture and its consumption via reaction with OH• radicals. Furthermore, an increase in pressure promotes the influence of CO methanation, thereby limiting the maximum achievable CH4 conversion.","PeriodicalId":725,"journal":{"name":"Petroleum Chemistry","volume":"66 1","pages":"73 - 87"},"PeriodicalIF":1.1,"publicationDate":"2026-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147558837","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The analysis was performed using HSC Chemistry software based on the principle of Gibbs free energy minimization. First, the influence of key operating parameters, such as the steam-to-carbon molar ratio (S/C), temperature, and pressure, on the H2 yield and concentration, carbon-containing gas concentration, and carbon deposition during the SG-SR process was investigated. The results showed that the optimal reaction conditions were 700°C, 0.10 MPa, and S/C = 4. Under these conditions, the H2 yield and concentration (on a dry gas basis) were 4.04 mol/mol and 84.05%, respectively. Subsequently, the impact of the CaO-to-carbon molar ratio (CaO/C) on SG-SESR, as well as the synergistic effects of S/C and CaO/C, were explored. The results demonstrated that when the temperature was controlled within 500–600°C with S/C = 6 and CaO/C = 2, the H2 yield reached 4.30 mol/mol, and the concentration peaked at 99.66%.

The [C4pyr]Cl/C2H2O4 DES was characterized by FT-IR and 1H NMR spectroscopy. This DES is capable of extracting thiophene-type sulfides due to the similar polarity of 1-butyl-pyridine and DBT. The –COOH groups within the [C4pyr]Cl/C2H2O4 DES are readily oxidized to ‒COOOH by H2O2, which susequently catalyzes the thiophene oxidation into sulfone in the model oil. The higher polarity of sulfone compared to that of thiophone enhances their solubility in the solvent. When the V(DES)/V(model oil) = 0.2, T = 50°C, and O/S = 6, the DBT removal rate reached 98.6% within 80 min. The catalytic activity of [C4pyr]Cl/C2H2O4 exhibited only a slight decrease after nine regeneration cycles. The apparent activation energy for DBT removal using [C4pyr]Cl/C2H2O4 was 33.3 kJ/mol.

The secondary objective was to utilize the produced materials for elimination air pollutants. Herein, a novel nanocatalyst, cobalt oxide (Co3O4) supported on reduced graphene oxide (rGO), was synthesized via an impregnation technology and employed for the oxidative desulfurization (ODS) of heavy naphtha in a Digital Baffle Batch Reactor (DBBR). The rGO nano-support was prepared from waste material through a catalytic reaction. The developed (Co3O4/rGO) nanocatalyst exhibited outstanding catalytic efficiency attributed to its effective impregnation, favorable pore size distribution, high activity, and large surface area, as confirmed by FESEM, EDX, XRD and BET analyses. The efficacy of the prepared nanocatalyst, combined with novel oxidant, performic acid, produced in situ from acetic acid and hydrogen peroxide (H2O2), was assessed in the DBBR under various ODS conditions, including reaction times (15, 25, and 35 min), impeller speeds (140, 200, and 260 rpm), and catalyst amounts (0.4, 0.8, and 1.2 g). The experimental results indicated that increasing the oxidation time, impeller speed, and catalyst amount enhanced desulfurization of the oil feedstock, yielding a cleaner fuel. Under optimal conditions (35 min reaction time, 260 rpm impeller speed, and 0.8 g of modified nanocatalyst), a sulfur conversion efficiency of 93.63% was achieved. The developed DBBR design demonstrated a high sulfur removal in only 35 min, a significant improvement compared to previous studies that required longer reaction times for similar or lower efficiencies.","PeriodicalId":725,"journal":{"name":"Petroleum Chemistry","volume":"66 1","pages":"112 - 126"},"PeriodicalIF":1.1,"publicationDate":"2026-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147559246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Catalytic testing revealed a correlation between the catalyst deactivation rate and the content of C19+ hydrocarbons in the products. When the C19+ content increased from approximately 40 to 55 wt %, the deactivation rate increased more than tenfold. Under optimized conditions (H2/CO = 2.3, P = 2.0 MPa, T = 193°C), the C19+ content reached ~46–50 wt %, and the deactivation rate was minimized. A long-term stability test over 500 h was used to project a catalyst cycle length, which was found to be at least 4000 h.
