In petrochemistry, petroleum geology and organic chemistry, cracking is the process whereby complex organic molecules such as kerogens or long-chain hydrocarbons are broken down into simpler molecules such as light hydrocarbons, by the …

2023年8月1日 · This review work tries to a) systemically introduce all the influence mechanisms of oil-cracking and presents new field cases; b) point out controversial and poorly understood issues related to oil-cracking; c) provide a guide to the estimation of the cracking extent of crude oils.

2023年6月10日 · Cracking is a process that removes large hydrocarbon molecules from raw crude oil to produce by-products such as cooking oil, ethanol, liquefied petroleum gas, diesel fuel, jet fuel, and other petroleum distillates.

However, a comprehensive review on crude oil cracking is yet to be conducted. This article systematically reviews the controlling factors of oil cracking from six as-pects, namely, oil...

2024年5月15日 · The cracking process of crude oil from the Ediacaran paleo-reservoir can be divided into four stages: cracking and transformation of the most unstable components, including NSOs and aromatics, and thermal cracking of the major components in the crude oil.

2024年11月15日 · We investigate molecular mechanisms of hydrocarbon cracking in heavy crude oil promoted by nanobubble collapse due to ultrasound-originated shock wave. Our millions-atom molecular dynamics simulations reveal rapid flow of molecules, causing nanobubble collapse and formation of energetic nanojet with a mushroom-like shape.

2024年12月29日 · Abstract: The natural cracking of crude oils in deep reservoirs has gained great interest due to continuously increasing depth of petroleum exploration and exploitation. Complex oil...

2022年5月4日 · In this review, catalyst formulations for the conversion of crude oil to light olefins have been discussed under the classifications: zeolite components, tuning of zeolite porosity, and matrix materials.

2012年7月26日 · A comparison of pyrolysis simulation experiments of crude oil, hydrous crude oil, and various water media under a constant temperature (350°C) and pressure (50 MPa) shows that water plays a large role in crude oil cracking to gas.

2024年3月28日 · Cracking is a pivotal technique employed in oil refineries to transform large and complex hydrocarbon molecules into smaller, more commercially viable components. This process is indispensable in refining crude oil, allowing the creation of essential products like heating oil, diesel fuel, and gasoline.
