To remove sulphur compounds from petroleum, it is treated with _______

1.	To remove sulphur compounds from petroleum, it is treated with __________(a) copper nitrate(b) copper oxide(c) magnesium chloride(d) sodium chlorideI had been asked this question during an internship interview.Question is from Mining of Petroleum topic in division Fuel Technologies of Applied Chemistry
Answer» Correct choice is (b) copper oxide For explanation I would say: The sulphur compounds can be removed by treating with copper oxide as the sulphur compounds are GET converted into the INSOLUBLE copper SULPHIDE.
