The quality of crude palm oil (CPO) is generally determined by the levels of free fatty acids (FFA). This helps in balancing the level of acidity during transportation and storage processes. However, high FFA in CPO is not good for consumer health.…
Herein, we present the production of jet and diesel range hydrocarbons from non-edible hexane-extracted Brassica carinata oil. The influence of four heterogeneous catalysts (two noble metal catalysts: Pd/C and Ru/C, and two transition metal…
Asphaltenes and paraffin are considered the molecules present in heavy crude oils that tend to form aggregates that cause high viscosity values. Understanding the molecular interactions occurring in such aggregation phenomena is essential to apply…
Corrosivity of petroleum fractions with the same total acid value (TAN) can be much different due to chemical structure differences of acidic species. To investigate corrosivity difference and interactions between different acidic species, acids with…
1 Scope This document specifies a test method for the determination of the content of mono-aromatic, di-aromatic and tri+-aromatic hydrocarbons in diesel fuels, paraffinic diesel fuels and petroleum distillates. This document defines two procedures,…
1 Scope This European Standard specifies requirements and test methods for marketed and delivered fatty acid methyl esters (hereafter known as FAME) to be used either as fuel for diesel engines and for heating applications at 100 % concentration, or…
Organic phase change materials (PCMs) are the most common heat storage components in latent heat based thermal energy storage (TES) systems. Among the different organic PCMs, fatty acids (FAs) have shown a real potential in important areas, such as,…
The analysis of resource use shows the annual dynamics of increasing the use of fossil fuels. A special place in the structure of the use of motor fuels falls on diesel fuel of petroleum origin
1 Scope This document specifies a test method for the determination of cetane numbers ("CN") in diesel fuel, using a standard single cylinder, four-stroke cycle, indirect injection engine. The cetane number provides a measure of the ignition…
Crude palm oil (CPO) is the main product of oil palm processing and is obtained through a series of unit operations. In a palm oil mill, the main unit operations involve applying saturated steam in the steriliser and digester. The high temperature…
Crude palm oil (CPO) and palm fatty acid distillate (PFAD) are rich sources of bioactive compounds. PFAD is a by-product of palm oil refinery that produce palm frying oil. Physical refining of palm oil by deodorization produces palm fatty acid…
In this work, microencapsulated phase change material (MEPCM) with the eutectic mixture of stearic acid (SA) and coconut oil (CO) as the core and melamine formaldehyde (MF) as the shell was developed by emulsion-polymerization method to be applied in…
The extraction of naphthenic acid from low-grade crudes offers economic and environmental advantages over chemical conversion or other separation processes. The properties of the solvent play critical roles for the successful implementation of the…
The supercritical carbon dioxide extraction of bio-crude, produced by hydrothermal liquefaction of lignocellulosic biomass, was investigated for pressures and temperatures in the range 112400 bar and 40120 C, corresponding to solvent densities in the…
Bio jet fuel becomes one of the feasible solutions for jet fuel inadequate supply in Indonesia. However, study in this field by far has been limited. In this study, bio jet fuel was synthesized from Crude Palm Oil (CPO) by Hydroprocessed Esters and…
Asphaltenes and paraffin are considered the molecules present in heavy crude oils that tend to form aggregates that cause high viscosity values. Understanding the molecular interactions occurring in such aggregation phenomena is essential to apply…
Bioremediation is a low-cost approach for crude oil spill remediation, but it is often limited by electron acceptor availability. In addition, the biodegradation products of crude oil contaminants are complex, and transformation pathways are…
Asphaltenes and paraffin are considered the molecules present in heavy crude oils that tend to form aggregates that cause high viscosity values. Understanding the molecular interactions occurring in such aggregation phenomena is essential to apply…
With the inevitable human innate aspirations for better urban mobility and sustainable economic development, bio-based transportation fuels are projected to play an essential role in the foreseeable automotive transportation sector.…
Hibiscus sabdariffa (Roselle) belongs to malvaceae family. Roselle seed oil is classified as semidry oil, the most fatty acids are linoleic, olic, palmatic, and stearic. Roselle seeds are a good source of lipid-soluble antioxidants, particularly…
Attempts to determine phenotypic predictors to identify high quality maize grain for different uses are noteworthy. This study aimed to assess the relationships among maize grain quality and some phenotypic characteristics of dent maize cultivars in…
Tucuma (Astrocaryum vulgare Mart.) is a native South American palm from the Amazon River drainage region. Tucuma fruits contain edible oils presenting high amounts of unsaturated fatty acids in the mesocarp and expressive amounts of saturated fatty…
The increasing energy demand in conjunction with greater environmental concern has lifted the development of sustainable energy sources, including materials for energy storage. The use of phase change materials (PCM) for thermal energy storage (TES)…
The fatty acid composition, triacylglycerol (TAG) profile, tocopherols, and oxidative stability of camelina and sophia seed oils, in the dark and under light, were evaluated. The significance of minor components to the stability of the oils was also…
