Abstract
Abstract An apparatus is provided for supplying heat required for a reforming reaction through the use of heat pipes adapted to transfer heat from a source to reforming reactants. Heat pipes extend between two chambers, with a catalyst material being disposed within one of the chambers, such that heat is extracted from a hot fluid and then introduced into the reforming chamber in which a hydrocarbon and steam react in the presence of the catalyst.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
157 words
An apparatus for producing synthesis gas including carbon monoxide and hydrogen, said apparatus comprising: (a) a first chamber adapted to receive a heated fluid, (b) a second chamber spaced apart from said first chamber and adapted to receive a stream including fluid hydrocarbon and steam, said stream being at a temperature lower than the temperature of said heated fluid, (c) a plurality of heat pipes disposed between said first and second chamber, a first portion of said heat pipes extending within said first chamber, a second portion of said heat pipes extending within said second chamber, (d) a catalyst material disposed within said second chamber, said steam reacting with said fluid hydrocarbon when in the presence of said catalyst to yeidl said synthesis gas, (e) means for introducing said heated fluid into said first chamber, (f) means for introducing said stream to said second chamber, and (g) means for removing said synthesis gas from said second chamber.
Claim 2
Independent Claim
157 words
An apparatus for producing synthesis gas including carbon monoxide and hydrogen, said apparatus comprising: (a) a first chamber adapted to receive a heated fluid, (b) a second chamber spaced apart from said first chamber and adapted to receive a stream including fluid hydrocarbon and steam, said stream being at a temperature lower than the temperature of said heated fluid, (c) a plurality of heat pipes disposed between said first and second chamber, a first portion of said heat pipes extending within said first chamber, a second portion of said heat pipes extending within said second chamber, (d) a catalyst material disposed within said second chamber, said steam reacting with said fluid hydrocarbon when in the presence of said catalyst to yeidl said synthesis gas, (e) means for introducing said heated fluid into said first chamber, (f) means for introducing said stream to said second chamber, and (g) means for removing said synthesis gas from said second chamber.
Claim 3
Dependent Claim
24 words
