Petroleum coke (petcoke) and refinery residues

Emerging technologies for catalytic gasification of petroleum residue derived fuels for sustainable and cleaner fuel production—An overview

“…In industrial-scale gasification or POx of petroleum-derived residues, catalysts are not prevalent. However, catalysts can be incorporated into gasification to attain reduced temperature operation, increased reaction rates, and unachievable output products using the traditional catalyst-free gasification process (Ulber, 2015;Mancuso and Arienti, 2017;Speight, 2015c;Luque and Speight, 2014). The heavy hydrocarbons' chemical nature and the presence of impurities in the fuel feed embody inherent catalyst activity (Speight, 2015a).…”

Development and Characterisation of Pantograph Slides for Railway Applications: A Short Review

“…With increasing emphasis on sustainable resource utilisation, the petrochemical industry has encountered several challenges in managing its diverse product streams. Even by-products of oil refining, like petcoke, prove challenging to utilise in a sustainable manner [33]. However, petcoke holds the potential for being converted into graphene, which presents an avenue to transform a carbon-rich byproduct into a valuable and versatile material with a multitude of applications, including in electronics, energy storage, composites, sensors, and more.…”

Increasing Biodegradability of a Real Amine-Contaminated Spent Caustic Problematic Stream Through Wao and Cwao Oxidation Using a High Specific Surface Catalyst from Petcoke

“…The fuel-grade green petcoke (PC) collected from a coker unit had the typical characteristics (included in the supplementary information) of a refinery coke [32], with a low specific surface area (ca. 10 m 2 /g), a CHNS distribution of 81.7 %, 3.7 %, 1.4 %, and 5.3 %, respectively, and heavy metals content of approximately 1,700 ppm of vanadium and 400 ppm of nickel (Table 2_SM).…”

“…It contains limited amounts of sulfur, metals, and non-volatile inorganic compounds. The most extensive use of petcoke is as a source of energy or carbon in different industrial applications [32]. Due to the majority use of coke as fuel in industries traditionally considered as a source of pollutant gas emissions, global demand of petcoke is expected to decline and, therefore, finding novel applications is key [33].…”
