METHOD FOR PREPARING A SORBENT

摘要

A method for preparing a sorbent precursor, which may be sulphided and used to remove heavy metals such as mercury from fluid streams, includes 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 including 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.
