Demetalation of hydrocarbonaceous feedstocks using monobasic carboxylic acids and salts thereof

摘要

Monobasic carboxylic acids or salts thereof are used to remove metals, particularly calcium and iron, from hydrocarbonaceous feedstocks. An aqueous solution of the acid is used to extract the metals from the feedstock prior to processing. Acetic acid is the preferred carboxylic acid.
