Abstract
A mineral carrier for those iron oxides which react to remove hydrogen sulfide and mercaptans from fluid streams. The new carrier avoids the problem encountered with wood chip beds of bed solidification which occurs when reacted oxide particles adhere to each other. Calcined montmorillonite, for example, possesses the necessary crush strength, porosity, insolubility in water and wettability, to maintain bed perviousness and avoid caking as reaction continues to the full capacity of the oxide.
