Question

What happens to the yield of heavier products as temperature increases?

(a) Increases

(b) Remains same

(c) Decreases

(d) None of the mentioned

I had been asked this question in class test.

This key question is from Catalyst topic in division Hydrocarbon Synthesis and Hydroformylation of Unit Processes

Answer 1

Correct option is (c) Decreases

To elaborate: The gasoline yield increases as the temperature increases, while the yield of heavier products decreases. A similar shift of products to lighter material occurs when the alkali content of the catalyst is decreased.
