Friedrich Bergius

“As early as 1912, we worked on the problem of the hydrogenation of organic substances with the aid of highly compressed hydrogen.”

“Even in the investigations into direct production of calcium peroxide in an alkali melt with highly compressed oxygen, it was found to be necessary to bring the high-pressure gas into contact with the suspension of lime in caustic alkali melt by agitation or some other means of mixing.”

“As early as 1910, Ludwig Landsberg had suggested that I should examine the problem of splitting heavy oils and oil residues into benzines.”
