“…This is particularly relevant for lower-value carbonintensive heavy oils, bitumen, oil sands, and coal-derived liquids. [77,78] However, it is not trivial, and it requires further research to improve the strength of the carbon fibres. [79] Overall, control autoxidation is a potential, economical, cheap, and sustainable pre-treatment process to produce carbon precursors.…”

Substantial amounts of low‐value light petroleum fractions and low‐value heavy petroleum fractions, such as light naphtha, HVGO, and vacuum residue, are generated during the upgrading and refining of conventional and unconventional petroleum resources. The oil industry emphasizes economic diversification, aiming to produce high‐value products from these low petroleum fractions through cost‐effective and sustainable methods. Controlled autoxidation (oxidation with air) has the potential to produce industrially important oxygenates, including alcohols, and ketones, from the low‐value light petroleum fractions. The produced alcohols can also be converted to olefin through catalytic dehydration. Following controlled autoxidation, the low‐value heavy petroleum fractions can be utilized to produce value‐added products, including carbon fiber precursors. It would reduce the production cost of a highly demandable product, carbon fiber. This review highlights the prospect of developing an alternative, sustainable, and economic method to produce value‐added products from the low‐value petroleum fractions following a controlled autoxidation approach.

“…One of the by-products of the technological process is heavy gas oil, which is characterised by a high content of sulphur, asphaltenes and the presence of aromatic compounds [2]. The main methods of processing heavy residues after catalytic cracking are gasification [3][4], visbreaking [5][6] and delayed coking [7][8]. These methods make it possible to process heavy fractions with maximum yield of demanded products (light fractions, vacuum gas oil and petroleum coke) [9].…”

The problem of utilisation of heavy oil by-products during oil refining is associated with high content of tarry asphaltene substances, coke, heavy metals and catalyst dust. A promising way to obtain commercial products from cube residues is low-temperature plasma chemical pyrolysis in liquid phase (NTP-plasma). The present work investigates the process characteristics of plasma-chemical pyrolysis of catalytic cracking residues (CCR) at current source voltages of 300- 700 V in order to optimise product composition and energy consumption. The gaseous NTP products of CCR pyrolysis contain (%mol): hydrogen (63.0-65.5), acetylene (21.8-23.6), methane (6.3-7.7), ethylene (2.7-3.4) and C3 - C6 hydrocarbons (1.9-3.7). Solid pyrolysis products are conglomerates of "sticky" particles of rounded shape in the size range from units to tens of microns. The maximum conversion of CCR pyrolysis was 78.9 % wt% at a minimum energy input of 3.3 kWh/kg at 500V.

“…Hence, it is applied prior to catalytic hydrocracking to maximize the liquid yield while lowering the production of coke . The typical pyrolysis processes, including delayed coking, visbreaking, and fluid coking, are widely used for the pretreatment of heavy oils. , However, due to the high concentration of sulfur and unsaturated compounds in the pyrolysis products, catalytic hydrocracking is applied to further process the products.…”
