A. Decrease in fuel-to-oil ratio: lol
With the feed rate and reaction temperature unchanged, an increase in the preheating temperature of the crude oil will cause ( a ).
With the feed rate and reaction temperature unchanged, increasing the preheating temperature of the crude oil will result in ( A ). A. Fuel-to-oil ratio decreases B. Fuel-to-oil ratio increases C. Conversion rate increases D. Coke yield increases
With the feed rate and reaction temperature unchanged, an increase in the preheating temperature of the feed oil will result in (A) a decrease in the reagent-to-oil ratio.

One daily activity question (single-choice question): With the feed rate and reaction temperature remaining constant, an increase in the preheating temperature of the crude oil will result in ( A ). A. Fuel-to-oil ratio decreases B. Fuel-to-oil ratio increases C. Conversion rate increases D. Coke yield increases
The reaction temperature is reached more quickly than before, the reaction distance increases, and the conversion rate rises.
