Abrégé anglais





The present invention is directed to system and method for processing material
to
generate syngas. A reactor chamber is implemented with a plurality of
electrodes that
can generate an arc within the chamber when electricity is applied to them.
The arc
can be used to create free radicals which along with the heat and light of the
arc
breakdown material comprising carbonaceous material, such as Municipal Solid
Waste (MSW), into gas components that form syngas. The syngas can be extracted

from the reactor chamber and be used for various commercial purposes. The
reactor
chamber may comprise a material feed system operable to move material from a
material input opening in the reactor chamber towards the electrodes at a
controlled
rate. Further, the reactor chamber may comprise a water injection system
within the
reactor chamber operable to inject water into the reactor chamber while
electricity is
applied to the electrodes. Yet further, the reactor chamber may comprise a gas

removal system within the reactor chamber operable to extract gas generated
from
breakdown of the material from a plurality of gas removal locations. The gas
removal
system may be integrated within the material feed system.
