Elimination of arsenic and mercury, useful for purifying liquid condensates from gas manufacture and crude oil, involves thermal non-catalytic treatment or catalytic treatment, optionally with hydrogenolysis

摘要

Elimination of arsenic (As) and mercury (Hg) in the presence of an adsorber, comprising nickel (Ni) deposited on a support, comprises thermal non-catalytic treatment or catalytic treatment in the absence of hydrogen (H2) or catalytic conversion in the presence of H2, which is added to the charge in advance and allows hydrogenolysis.
