Feed purification

To protect any downstream catalysts in ammonia, methanol and hydrogen gas productions poisoned, Clariant developed the ActiSorb series of catalysts and adsorbents for the purification of almost all hydrocarbon feed-stocks. This purification is normally a combination of a reaction using a pre-treatment catalyst, i.e. hydrogenation, followed by adsorption with the ActiSorb adsorbent. The feed purification steps successively may as mercury removal, hydrodesulfurization or hydrotreating, chloride removal, and sulfur removal.
