Which German chemist contributed to crude oil refining by removing sulfur?

• A. Herman Frasch
• B. Carl von Linde
• C. Justus von Liebig
• D. Fritz Haber

Answer: (A)

Sulfur handling is a major part of refining because removing sulfur from fuels improves environmental performance and protects catalysts. The German chemist who made a pivotal contribution here is Herman Frasch, who developed the Frasch process to extract elemental sulfur from underground deposits. This breakthrough dramatically expanded the availability of sulfur, which in turn supported the development of refining practices that deal with sulfur compounds and the sulfur industry as a whole. The other figures are known for different achievements: refrigeration and industrial gas processes (Linde), general chemical theory and organic chemistry (Liebig), and ammonia synthesis (Haber). So Frasch’s work on obtaining sulfur provided the foundation that refining methods later built upon to remove sulfur from crude oil.
