Catalytic fast pyrolysis (CFP) is an advanced controlled process of biomass thermal decomposition designed to produce high volumes of ready-to-use transportation biofuels or to provide improved quality bio-oil for subsequent refining or upgrading.…
Currently, the fuel oil for transportation and industry is produced mostly from fossil fuels. Because fossil fuels are a limited resource, biomass could be an alternative resource. Empty fruit bunch (EFB) is biomass waste from fresh fruit bunch…
The direct conversion of crude oil to light olefins is considered one the cheapest and most reliable sources of petrochemical primary feedstocks. Unlike in the past when refineries operated to produce mainly transportation fuels, such as gasoline and…
There is an increasing global attention toward hydrogen as a green energy carrier, primarily because of the environmental concerns associated with global warming issues. It is expected that the produced hydrogen from various sources may be injected…
Petroleum refinery has been developed for production of transportation fuel with light alkenes and benzene, toluene, ethylbenzene, and xylenes (abbreviated BTEX), but global market demands are shifting to chemicals produced from light alkenes and…
As a type of environmentally friendly and renewable energy, hydrogen energy has gradually matured its production technology, and its cost has dropped significantly. It will usher in a period of opportunity for rapid development. The key to the…
Upgrading heavy crude oil from East of Baghdad oilfield using a high pressure reactor with steam supplied and toluene as hydrogen donor has been investigated through aquathermolysis process. Synthesized Zn/HY Zeolite, which is characterized by XRD,…
The technology of methane storage by the adsorption-hydration hybrid (AHH) combines the adsorbed natural gas (ANG) and natural gas hydrate (NGH) methods to store gas in porous materials. This technology can overcome the shortcomings of ANG and NGH…
The thermal decomposition method has been able to convert of real municipal solid waste (MSW) into Bio-Crude Oil (BCO) which is mainly contained hydrocarbon fuel such as light oil (gasoline) and heavy oil (diesel). By this method, sustainable MSW…
High-sour natural gas usually contains organosulfurs besides H2S, the majority of which exist in the form of mercaptans. These impurities of organosulfurs are required to be removed efficiently and economically for commercial application and the…
The removal of acidic gases and impurities from gas mixtures is a critical operation in the oil and gas industry. Several separation techniques, e.g., cryogenic fractionation, polymeric membranes, zeolites, and metalorganic frameworks, are employed…
Improving predictive models for noble gas transport through natural materials at the field-scale is an essential component of improving US nuclear monitoring capabilities. Several field-scale experiments with a gas transport component have been…
A thermal processing of waste tires in the presence of a natural zeolite catalyst from the "Tayzhuzgen" field (Eastern Kazakhstan) is detailed. The hydrogen sources utilized were heavy residues from oil refinement. The elemental and phase composition…
Among the methods for confirming the natural origin of flavor compounds, 13C measurements using IRMS technique are becoming increasingly important. EA-IRMS measures can suffer from errors caused by the volatility of the analyzed compounds and the…
The direct conversion of crude oil to light olefins is considered one the cheapest and most reliable sources of petrochemical primary feedstocks. Unlike in the past when refineries operated to produce mainly transportation fuels, such as gasoline and…
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
The Rio Grande Valley (Neuquen Basin, Argentina) is a large oil field where voluminous igneous sill complexes are emplaced in different levels of the sedimentary sequence in a fold and thrust belt setting. These sills are predominantly emplaced in…
The aim of the current study was to investigate and study adsorption and nanofiltration systems for separation of total petroleum hydrocarbons (TPH) from wastewater generated by an oil refinery in Bushehr, Iran. In the first step (previous study),…

Petroleum degrading enzymes can be used as an alternative way to improve petroleum bioremediation approaches. Alcanivorax borkumensis is an alkane-degrading bacteria that can produce petroleum degrading enzymes such as alkane hydroxylase and lipase.…
The role of natural gas in mitigating greenhouse gas emissions and advancing renewable energy resource integration is undoubtedly critical. With the progress of hydrocarbons exploration and production, the target zones become deeper and the…
The Brazilian offshore pre-salt cluster is one of the most important recent discoveries of hydrocarbon resources in the world. These fields normally present high CO2 content (more than 10%) and also high Gas Oil Ratio (GOR), thus might limit the oil…
There is an increasing global attention toward hydrogen as a green energy carrier, primarily because of the environmental concerns associated with global warming issues. It is expected that the produced hydrogen from various sources may be injected…
This article provides an overview of a variety of applications of 29Si NMR to materials, with an emphasis on solid-state 29Si NMR of siloxane polymers, silicates, functionalized silica, porous materials, zeolites, and glasses. The unique features of…
C4 hydrocarbons are valuable fractions of the oil and gas processing industry due to their market size and importance as raw materials in the manufacture of several products. C4s are derived from fluid catalytic cracking (FCC) and from natural gas…
