Annatto‐Derived Carotenoids (Bixin and Norbixin) As Biodiesel Antioxidants: Characterization and Effects on Oxidative Stability (Rancimat and PetroOXY)

Journal of the American Oil Chemists' Society, EarlyView.
Annatto‐derived bixin and norbixin were characterized and evaluated as natural antioxidants for soybean biodiesel. Their antioxidant performance and effects on oxidative stability were assessed using DPPH, Rancimat, and PetroOXY methods. ABSTRACT The increasing use of eco‐friendly fuels is increasing the production of biodiesel but soybean biodiesel is

Catalytic Pyrolysis of Waste Polystyrene Over Fe–B Composite Catalyst for Enhanced Liquid Fuel Production

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Healthcare derived polystyrene waste represents a growing and under addressed fraction of plastic waste streams due to contamination risks and limited recyclability. This study aims to investigate the valorization of waste polystyrene foam through catalytic and noncatalytic pyrolysis pathways to evaluate product yield distribution and identify

Numerical Study of MHD Hybrid Nanofluid Flow With Multiple Slip Effects Over a Variable Porous Stretching Surface

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This work discusses the thermal performance of magnetized hybrid nanofluid flow over a variable porous stretchable surface, emphasizing the underlying physical mechanisms governing heat and mass transfer. The Cattaneo–Christov flux model is used in place of Fourier's and Fick's laws to incorporate relaxation effects, ensuring a more realistic ...

Exploring Influence of MgO/Na2O on Melting Characteristics and Viscosity–Temperature Characteristics of Coal Slags Under Entrained Flow Gasification Condition

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Characteristics of high alkali in Zhundong coal ash may cause ash‐related slag discharge problems at entrained‐flow‐bed (EFB) gasifier. In this study, through exploring melting characteristics and viscosity–temperature characteristics, it is found that MN05, MN14, and MN23 show low FTs (< 1160°C).

Synergistic Effect on Enhanced Oil Recovery in High Salinity Carbonate Reservoirs Using a Novel PEI‐Functionalized Carbon Nanotube Nanocomposite

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Enhancing oil recovery (EOR) in mature reservoirs is hindered by high interfacial tension (IFT) and oil‐wet rock formations, especially under harsh, high‐salinity conditions. This study aims to overcome these limitations by synthesizing a novel carbon nanotube nanocomposite covalently grafted with polyethylenimine and non‐covalently ...

CuO‐CuAl2O4 Catalyst for Synthesis of 1‐Methylindole by Alcohol Amine Method

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Cu‐based catalysts used for the vapor‐phase synthesis of 1‐methylindole from N‐methylaniline and ethylene glycol are prone to Cu sintering and deactivation under the reaction conditions. In this work, CuO‐CuAl2O4 catalysts were prepared by a coprecipitation method and applied to the synthesis of 1‐methylindole via alcohol amine route.
