Abstract:
Integrated liquid fuel catalytic partial oxidation (CPOX) reformer and fuel cell systems can include a plurality or an array of spaced-apart CPOX reactor units, each reactor unit including an elongate tube having a gas-permeable wall with internal and external surfaces, the wall enclosing an open gaseous flow passageway with at least a portion of the wall having CPOX catalyst disposed therein and/or comprising its structure. The catalyst-containing wall structure and open gaseous flow passageway enclosed thereby define a gaseous phase CPOX reaction zone, the catalyst-containing wall section being gas-permeable to allow gaseous CPOX reaction mixture to diffuse therein and hydrogen rich product reformate to diffuse therefrom. The liquid fuel CPOX reformer also can include a vaporizer, one or more igniters, and a source of liquid reformable fuel. The hydrogen-rich reformate can be converted to electricity within a fuel cell unit integrated with the liquid fuel CPOX reactor unit.

Abstract:
A process for preparing acetylene and synthesis gas by partial oxidation of hydrocarbons with oxygen, by first separately preheating the hydrocarbon gas and oxygen gas, and then reacting the gases and cooling the products rapidly. The reactor wall is blanketed with a purge gas stream, introduced through a plurality of feed lines. These feed lines deliver purge gas in a vector direction within a 10° angle of the main flow direction of the reactive gas stream. The purge gas is delivered at multiple stages relative to the main flow direction of the reactive gas stream, and the free cross section of the firing space available to the reactive gas stream, at the height of the feed lines of the purge gas stream, is approximately constant.
