Comprehensive two-dimensional gas chromatography (GC × GC) has impacted the workflow of GC-based methods used in petroleum industry. Application of GC × GC to petroleomic investigations have guided sample preparation to faster, cleaner, and more…
Electrification and decarbonization of the chemical industry are the keys to achieve carbon neutrality for human society, which necessitates the transition from fossil resource-based chemical production to renewable energy-based chemical production.…
In Thailand, onshore drill cuttings (DC) contaminated with total petroleum hydrocarbon (TPH) are currently transported off-site for incineration, causing high transportation cost and potential leakage to the environment. To address the issues, we…
Ultra-high molecular weight poly--olefins are widely used as drag reducing agents (DRAs) for pipeline transportation of oil and refined petroleum products. The synthesis of polyolefin DRAs is based on low-temperature ZieglerNatta (ZN) polymerization…
Engine experiments were performed for measurement of regulated, unregulated, and particulate emissions using a 2.2 L transportation compression ignition engine fueled with blends of diesel and biodiesels derived from Jatropha and waste cooking oils.…
In this work, modified ethylene-vinyl acetate (EVA)-based copolymers were synthesized by graft copolymerization of hydrophobic monomers onto commercial EVA using a low energy electron beam (EB). The mechanism of graft copolymerization was studied by…
Pour point depressant is one of the effective approaches to improve the low temperature fluidity of high-wax crude oil. Understanding the gelation of waxy oil on the pipe wall and the mechanism of pour point depressant is of great significance for…
Fast pyrolysis is a controlled process of biomass thermal decomposition designed to yield high volumes of liquid bio-oil, which can subsequently be upgraded into high energy density transportation biofuels such as green gasoline, green jet fuel and…
The hydrate-based solidified natural gas (SNG) technology is a promising approach for natural gas storage and transportation. One challenge of this technology is to enhance the hydrate formation kinetics and achieve mild storage conditions. This work…
In the pipeline transportation of waxy crude oil when the temperature of the waxy crude oil drops lower than the wax appearance temperature (WAT), wax precipitates continuously from oil phase, which brings a series of negative impacts on pipeline…
Light alkanes from shale resources can potentially be converted to an easy-to-transport liquid hydrocarbon product by catalytic dehydrogenation followed by catalytic oligomerization. The chemical species in the liquid product and their concentrations…
In Malaysia, solid depositions of paraffin wax in the inner walls of production and transportation pipelines, and on the surface of production equipment have been identified as the utmost challenge in production and transportation of crude oil. In…
Clathrate hydrates are one of the proposed mediums for transportation and storage of natural gas. Among the known hydrate structures, structure H seems the most fitting crystal due to its moderate formation pressure and high storage capacity. In the…
The direct cracking of crude oil is an interesting option for producing cheaply large amounts of petrochemicals. This may be carried out with catalyst and equipment similar to that of catalytic cracking, but at a temperature range between that of…
The combustion of natural gas reduces fuel cost and generates less emissions of carbon dioxide and particulate matter (PM) than diesel and gasoline. Replacing diesel by natural gas in internal combustion engines is of great interest for…
The present work concerns the study of rich laminar premixed CH4/C2H6/C3H8/O2/N2 flames operating at two equivalence ratios ( = 1.66 and 2.05) and low pressure (80 Torr). In the case of the flame = 2.05, the influence of pressure was studied between…
Comprehensive information about the hydrate formation and dissociation conditions is necessary for design and operation of different processes in the petroleum industry. This study investigated the natural gas hydrate equilibrium conditions in the…
During the process of distributing natural gas to urban users through city gate stations, hydrate is easy to form due to the existence of throttling effect which causes safety risks. To handle this problem, a program to quickly calculate hydrate…
Abstract: The state-of-the art in the catalytic conversion of natural gas containing methane as the main component to valuable chemicals and fuels is reviewed. Methane conversion processes are of considerable importance to society
Malaysia and Indonesia are the largest palm oil producers worldwide. In palm oil production, approximately one tonne of empty fruit bunch (EFB) will be generated as waste for every one tonne of palm oil produced. Currently, these fresh EFB are still…
The composition of petroleum hydrocarbons in oily sludge is complex, and it is difficult to reveal the interaction between components in the pyrolysis process only by the macroscopic analysis results of products. Five compounds, namely n-dodecane,…
The conversion of mechanical to chemical energy offers an option for long-term and versatile energy storage. It was already proven that piston engines can be used as flexible reactors for energy conversion. Here, a novel method for energy conversion…
