(Catalytic cracking term explanation) Reaction time: The time during which the feedstock reacts in contact with the catalyst. =============================
Contact time between crude oil and catalyst in the riser
Reaction time is the residence time of the feed oil and gas in the riser
Residence time of oil and gas in the riser.
The residence time of the raw material in contact with the catalyst for the reaction.
It refers to the time required for one or several raw materials, under the action of a catalyst and at certain temperature and pressure conditions, to transform into one or several new substances.
The residence time of the reactive hydrocarbons in the riser is the reaction time
The time required for the crude oil to undergo chemical reactions on the catalyst. The typical catalytic cracking reaction time is around 3 seconds.
