Smoke point of kerosene is the
A. Time after which smoking starts on burning
B. Temperature at which smoking starts
C. Maximum height of flame (in mm) without causing smoking, when burnt in a standard lamp
D. None of these
Answer: Option C
Solution(By Examveda Team)
In petroleum refinery engineering, the smoke point of kerosene refers to the maximum height of flame (in mm) without causing smoking, when burnt in a standard lamp (Option C).The smoke point is an important parameter that indicates the quality of kerosene or other liquid fuels. It represents the maximum temperature at which the fuel can be burned without producing visible smoke. When the flame exceeds this height, incomplete combustion occurs, resulting in the emission of smoke.
Therefore, the correct option is Option C: Maximum height of flame (in mm) without causing smoking, when burnt in a standard lamp.

Aniline point test of an oil qualitatively indicates the __________ content of an oil.
A. Paraffin
B. Olefin
C. Aromatic
D. Naphthene
Option c is correct
The smoke point is the maximum flame height in millimeters at which kerosene will burn without smoking, tested under standard conditions, this test method provides an indication of the relative smoke producing properties of kerosene
The smoke point is related to the hydrocarbon type composition of such fuels. Generally the more aromatic the fuel the smokier the flame. A high smoke point indicates a fuel of low smoke producing tendency
The maximum height of flame obtainable without smoking, termed the "smoke point." is greatest with paraffins. Considerably lower with naphthenic and much lower still with aromatics. As the smoke point is high like the paraffinic compounds it will have low smoking tendency ( less able to produce smoke). Inversely, the low smoke point like in aromatic compounds has high smoking tendency to produce smoke.
