Uhde, combined autothermal reformer

CAR [Combined autothermal reforming] A "reforming process for making "syngas from light hydrocarbons, in which the heat is provided by partial oxidation in a section of the reactor. Developed by Uhde and commercialized at an oil refinery at Strazske, Slovakia, in 1991.

Uhde has developed its Combined Autothermic Reformer (CAR) and has successfully operated a demonstration unit, which produces 13,000 m /h of process gas at 1.7 MPa [28]. CAR is a combination of reforming exchanger and r partial oxidation in a single vessel. The mixture of natural gas and steam is passed through the tubes filled with catalyst. These tubes are heated externally by hot reformed gas from the partial oxidation section. No commercial CAR unit has been installed as of late 1994. 

Combined Autothermal Reforming. In the combined autothermal reforming (CAR) process developed by Uhde (27), the HSR process and the ATR process are combinedin to one reactor (Fig. 3). 

Elimination of the reforming furnace is likely to be a significant trend in future ammonia plants. Similar technology is also under development by Uhde with their Combined Autothermal Reformer or although this process requires the...
