(under subclass 208) Processes wherein mineral oil is desulfurized by the use of silicon or a compound thereof.
(1) Note. This subclass contains, for example, desulfurization processes wherein silicon oxides, per se, or combined as silicates (e.g., clays) are used.
SEE OR SEARCH THIS CLASS, SUBCLASS:
250, for manipulative processes of desulfurizing mineral oils using unnamed solid contact agents, but which may be disclosed as being the clay type.
299+, for other processes of refining mineral oils by treating the same with solid contact agents, and particularly subclass 307 for the use of silicon containing treating agents, e.g., clay, in such processes.
