Abstract: Hydraulic binder-contg. nickel catalyst is produced by pptg. Ni5MgAl2(OH)16.CO3.4H2O or Ni6Al2(OH)16.CO3.4H2O from aq. soln. onto suspended carrier particles, separating the particles carrying the above salt, drying, calcining, mixing with a calcium aluminate cement and water, moulding, allowing to set, and reducing the salt to produce nickel catalyst. The calcium aluminate cement is used in an amt. of 5-40 wt % w.r.t. the calcined mixt. The catalyst is used for methanation of gases contg. carbon oxides (usually 10-32 wt % CO) and hydrogen at 250 degrees C. Within this temp. range, the catalyst has good mechanical strength and activity.

Abstract: Methane-contg. gases are produced from 2-30C hydrocarbons, using Ni on a carrier as catalyst, by passing steam at pressures >1 atmos. and pre-heating to >250 degrees C to produce a temp. of 300-600 degrees C in the catalyst bed, in which the catalyst is simultaneously regenerated by wholly or partly replacing the hydrocarbon feed with methanol. Used for the mfr. of rich gases e.g. for use as natural gas substitutes. De-activation of the catalyst by carbonaceous deposits, as shown by a steady migration of the temp. profile through the bed, is reversed. Subsequent de-activation is not significantly faster e.g. half the original activity, as measured in bed thickness, can be maintained. Production of gas is not interrupted or permanently reduced.

Abstract: H2S-containing gases are desulfurized by direct catalytic oxidation of the H2S to elementary sulfur by means of oxygen-containing gases in a tube reactor, with indirect removal of the heat of reaction by means of a coolant and with condensation of the sulfur formed, wherein either the catalyst is present in the jacket space around the tubes and the coolant is present in the tubes of the reactor or the coolant is present in the jacket space around the tubes and the catalyst is present in the tubes of the reactor, and the catalyst fills the tubes of the tube reactor or the jacket space around the tubes over the entire cross-section of the tubes or the jacket space respectively, the exit temperature of the gaseous reaction mixture leaving the tube reactor is kept at 180 DEG -400 DEG C. and the sulfur formed in the tube reactor is separated out of the reaction mixture, obtained in the reactor, in a condensation stage downstream of the reactor.

Abstract: A process for preventing deposits in the pipes of waste heat boilers employed for cooling gases in the partial autothermal oxidation of fossil fuels to prepare hydrogen or synthesis gases, wherein the pipes are flushed, at the operating temperature, with hydrogen-containing gases which contain little or no H2S.
