Abstract
The method of capturing gaseous heavy metals disclosed herein includes exposing a stream of vapor including the gaseous heavy metals to a reactor bed of carbon (C) and aluminum (Al) in the form of pellets and granules. The gaseous heavy metals include mercury (Hg), mercury oxide (HgxOy), and other heavy metals in ionized or oxidized form.
Claims30
A method of capturing gaseous heavy metals, the method comprising:
- generating smoke by vaporizing waste material in a pyrolysis chamber;
- oxidizing the smoke in a plasma chamber to generate a stream of vapor including the gaseous heavy metals;
- and
- exposing the stream of vapor including the gaseous heavy metals to a reactor bed of carbon (C) and aluminum (Al) in the form of pellets, ribbons or granules.
1 more element
(canceled)
A system for removing heavy metals, the system comprising:
- a reaction vessel configured to receive a stream of vapor from its vertically top end and to release the vapor from its bottom end;
- and
- a plurality of media layers configured within the reaction vessel, the plurality of media layers including one or more mixture layers including a combination of aluminum and carbon granules and one or more aluminum ribbon layers, wherein the one or more mixture layers and the one or more aluminum ribbon layers are arranged alternatively along the vertical length of the reaction vessel.
(canceled)
A method of capturing gaseous heavy metals from a vapor stream, the method comprising:
- exposing the vapor stream including the gaseous heavy metals to a reactor bed of
- alternating layers of carbon (C) and aluminum (Al), the Al layer comprising Al ribbons.
