Method for preparing a sorbent

摘要

A method is described for preparing a sorbent precursor comprising the steps of: (i) mixing together an inert particulate support material and one or more binders to form a support mixture, (ii) shaping the support mixture by granulation in a granulator to form agglomerates, (iii) coating the agglomerates with a coating mixture powder comprising a particulate copper compound and one or more binders to form a coated agglomerate, and (iv) drying the coated agglomerate to form a dried sorbent precursor. The sorbent precursor may be sulphided and used to remove heavy metals such as mercury from fluid streams.
