A typical fluid catalytic cracking unit in a petroleum refinery. Fluid catalytic cracking (FCC) is the conversion process used in petroleum refineries to convert the high-boiling point, high-molecular weight hydrocarbon fractions of petroleum (crude oils) into gasoline, alkene gases, and other petroleum products.
A de-asphalter is a unit in a crude oil refinery or bitumen upgrader that separates asphalt from the residuum fraction of crude oil or bitumen.The primary purpose of the separation is to remove contaminants (asphaltenes, metals) from the feed that would cause rapid deactivation of catalysts in downstream processing units.
Hypixel Network, [3] simply known as Hypixel, is a Minecraft server that hosts minigames. It was released on April 13, 2013 by Simon "hypixel" Collins-Laflamme and Philippe Touchette, and is managed and run by Hypixel Inc. [ 4 ] Hypixel is only available on the Java Edition of Minecraft, [ 5 ] but briefly had a Bedrock variant.
However, independently of the crude oil used in the refinery, all catalysts require a maximum final boiling point of the naphtha feedstock of 180 °C. Normally, the catalyst can be regenerated perhaps 3 or 4 times before it must be returned to the manufacturer for reclamation of the valuable platinum and/or rhenium content.
This is a list of oil refineries. The Oil & Gas Journal publishes a worldwide list of refineries annually in a country-by-country tabulation that includes for each refinery: location, crude oil daily processing capacity, and the size of each process unit in the refinery. For some countries, the refinery list is further categorized state-by-state.
The Penex process is a continuous catalytic process used in the refining of crude oil. It isomerizes light naphtha (C 5 /C 6) into higher-octane, branched C 5 /C 6 molecules. It also reduces the concentration of benzene in the gasoline pool. [1] It was first used commercially in 1958. [2]
