Optimization of Saponification Process for Quantification of Individual and Total Tocopherols and Phytosterols in Canola Oil Refining By‐Products

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT In this study, saponification variables were optimized using a face‐centred central composite design‐response surface methodology. The variables included reaction temperature (50°C–120°C), reaction time (30–180 min), KOH concentration (0.5–3 M) and pyrogallol concentration (0–1% w/v).

Activated Clays and Their Potential in the Cement Industry

, 2021
The thermal activation of clays to produce highly reactive artificial pozzolans on a large scale is one of the most important technologies developed on an industrial scale to reduce CO2 emissions in cement manufacture. This technical document deals with the scientific basis for the thermal activation of clays to produce an extraordinarily high quality ...

Green Fuel Combustion Synthesis of CeO2 and Ag/CeO2 Nanoparticles for Photocatalytic and Antibacterial Applications

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Silver‐doped cerium oxide nanoparticles (Ag/CeO2 NPs) were synthesized using Ricinus communis seed extract as a bio‐derived fuel in a solution combustion method. The combustion reaction, carried out at 450°C with AgNO3 and (NH4)2[Ce (NO3)6] as metal precursors, produced CeO2 and Ag/CeO2 NPs.

Synergistic Physicochemical Inhibition of Reactive Shale Formations Using Hydrothermally Synthesized Hydroxyapatite Nickel Tungstate Nanocomposites in Water‐Based Drilling Fluids

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Wellbore instability driven by the volumetric expansion of reactive shale formations remains a primary operational challenge in modern drilling engineering, causing severe mechanical failures and substantial economic deficits. The objective of this study is to formulate and evaluate a novel dual‐action chemical additive capable of ...

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

Synergistic Advanced Oxidation and Physicochemical Treatment Strategies for Antibiotic Removal and Resistance Mitigation in Water

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The presence of antibiotics in water not only causes environmental pollution but also increases the growth of antibiotic‐resistant bacterial genes, which pose serious threats to human beings and other water residents. Large numbers of people are reportedly affected by the resistant bacterial genes, as many broad‐spectrum antibiotics are not ...
