The process also produces light hydrocarbon liquids which are used to upgrade the heavy oil. An apparatus for continuously upgrading heavy oil to produce light hydrocarbon gases which are recycled in the as a carrier gas used in spark-discharge hydrocarbon cracking within the apparatus. The apparatus also produces light hydrocarbon liquids which are used to upgrade the heavy oil.

Disclosed is a gas collection apparatus used in manufacturing a semiconductor. The apparatus includes: a housing having a chamber formed therein; a heating member installed in the housing to heat cobalt-carbon gas introduced into the chamber; a cobalt deposition member installed across the chamber of the housing to deposit cobalt composite; and a cooling member that induces carbon composite to be solidified and deposited while rapidly cooling the carbon composite.

This disclosure provides a halogenated activated carbon composition comprising carbon, a halogenated compound and a salt. In some embodiments, the halogenated compound and the salt comprise a naturally occurring salt mixture, as may be obtained from ocean water, salt lake water, rock salt, salt brine wells, for example. In some embodiments, the naturally occurring salt mixture comprises Dead Sea salt.

Chromium particulate emissions in flue gas can be reduced or minimized by incorporating a thin layer bed of a catalyst within the flue gas flow path of a furnace, boiler, or other furnace environment that includes Cr-containing surfaces. The thin layer bed of catalyst can correspond to, for example, a honeycomb monolith with catalyst supported on the monolith surface, so as to provide a high contact area while forcing all of the flue gas to pass through the catalyst bed. The honeycomb monolith structure and the depth of the bed can be selected to provide a reduced or minimized pressure drop across the catalyst bed, such as a pressure drop of 0.25 kPa (1.0 inches of water) or less. Exposing the Cr-containing flue gas to the thin layer catalyst bed can result in a treated flue gas with a lower content of Cr.

Capturing mercury or arsenic heavy metal from a moist gas containing water vapour, by: a) cooling the moist gas by heat exchange with a heat transfer fluid produced in e) in order to obtain a gas cooled to a temperature Tf, vaporizing the heat transfer fluid; b) separating condensed water and condensates contained in the cooled gas obtained in a) obtaining a gas depleted in water and a liquid stream containing water; c) compressing vaporized heat transfer fluid obtained from a) obtaining compressed heat transfer fluid; d) heating water-depleted gas by heat exchange with compressed heat transfer fluid obtained in c) obtaining a cooled heat transfer fluid and a gas reheated to a temperature Tc; e) decompressing cooled heat transfer fluid obtained in d), recycling heat transfer fluid to a); f) contacting reheated gas obtained in d) with a capture mass for said heavy metal.

The invention relates to a method of reducing carbon dioxide and metal-containing dust and, more particularly, to a method of simultaneously reducing carbon dioxide and metal-containing dust by passing an off-gas, which contains carbon dioxide or carbon dioxide and metal-containing dust, through a reactor in which a sulfur-oxidizing microorganism is grown using carbon dioxide as a carbon source to produce sulfuric acid, and producing metal sulfates (MeSO.sub.4) by reaction of the produced sulfur acid with metal components present in the off-gas.

The present disclosure provides a method of separating Mo-99 from W-187 from a solution comprising Mo-99 and W-187. The method comprises contacting a tridentate diglycolanude ligand with a solution comprising Mo-99 and W-187 and eluting W-187 from the tridentate diglycolanude ligand to thereby an eluate comprising W-187.

A system and method for processing unconditioned syngas first removes solids and semi-volatile organic compounds (SVOC), then removes volatile organic compounds (VOC), and then removes at least one sulfur containing compound from the syngas. Additional processing may be performed depending on such factors as the source of syngas being processed, the products, byproducts and intermediate products desired to be formed, captured or recycled and environmental considerations.
