Durable, porous sulfur sorbents useful in removing hydrogen sulfide from hot coal gas are prepared by water pelletizing a mixture of fine zinc oxide and fine iron oxide with inorganic and organic binders and small amounts of activators such as sodium carbonate and molybdenite; the pellets are dried and then indurated at a high temperature, e.g., 1800° C., for a time sufficient to produce crush-resistant pellets.

Activating zinc ferrite oxidative dehydrogenation catalysts

Method of activating zinc ferrite oxidative dehydrogenation catalysts

The present invention is directed to a hydrogen generating and regenerating system which supplies combustion gas and steam pressure from water to produce inexpensive energy. The system comprising of the process to supply hydrogen and oxygen over a porous metallic catalyst bed in a combustion chamber and igniting producing heat for boiler water to provide steam to turn a steam turbine. Then catalytically reforming steam over porous material producing hydrogen in a converter reactor zone and subsequently also producing combustion gas pressure in the combustion chamber that flow through the converter to turn a gas turbine, a compressor and a generator. The system passes a second catalytic promoter through the converter reactor zone to reactivate porous material by to produce additional hydrogen without using hydrogen generated. The gas combustion pressure passes through the turbine and heat exchangers preheating recycled water providing optimum efficiency and creating clean cheap electrons.
