What was the name of the German Chemist who was first able to take sulfur out of crude oil?

• A. Rudolf Diesel
• B. Herman Frasch
• C. Gottlieb Daimler
• D. August Kekulé

Answer: (B)

The key idea here is recognizing who pioneered practical sulfur production on an industrial scale. Herman Frasch was a German chemist who invented the Frasch process, a method for extracting elemental sulfur from underground deposits. The technique involves lowering pipes into the sulfur beds, injecting superheated water to melt the sulfur, and using air to keep the melt movable so it can be pumped to the surface. This breakthrough made large-scale sulfur supply feasible, which in turn supported industries that rely on sulfur compounds, including petroleum refining. The other names listed are notable for engines or chemistry theory, not for pioneering sulfur extraction.
