The present invention relates to a process for nonoxidatively dehydroaromatizing a reactant stream comprising C-C-aliphatics by converting the reactant stream in the presence of a catalyst in a reaction zoneto a product stream P comprising aromatic hydrocarbons, and regenerating the catalyst whose activity has been reduced by deposited coke with a hydrogen-comprising mixture H in a reaction zone, wherein at least a portion of the deposited coke is converted to methane and at least a portion of the methane formed is fed to reaction zone

Process for obtaining benzene, toluene (and naphthalene) from C1-C4-alkanes with co-dosage of hydrogen at a separate location

The present invention relates to a catalyst for dehydroaromatizing C-C-aliphatics, said catalyst being obtainable by twice treating a zeolite from the group of MFI and MWW with NH-containing mixtures, in each case with subsequent drying and calcination. The catalyst comprises molybdenum and, if appropriate, as further elements, Cu, Ni, Fe, Co, Mn, Cr, Nb, Ta, Zr, V, Zn and/or Ga. The present invention further provides a process for dehydroaromatizing a mixture comprising C-C-aliphatics by conversion in the presence of the catalyst.

Catalyst for the dehydroaromatisation of methane and mixtures containing methane

The present invention relates to a process for nonoxidative dehydroaromatization of aliphatic hydrocarbons by converting a reactant stream comprising aliphatic hydrocarbons in the presence of a catalyst which comprises at least one metallosilicate as a support, at least one element selected from the group of Mo, W and Re as an active component and at least one further transition metal which is not a noble metal as a dopant, wherein the catalyst is regenerated regularly with hydrogen under nonoxidative conditions. The further transition metal used is preferably Fe, Ni, Cu and Co.

Method for the dehydroaromatisation of mixtures containing methane by regenerating the corresponding catalysts that are devoid of precious metal

Processes comprising: providing a starting material comprising monoethanolamine; and reacting the starting material with ammonia in the presence of a heterogeneous transition metal catalyst to form a reaction product comprising one or more ethylene amines; wherein the catalyst comprises a catalytically active composition, which prior to treatment with hydrogen, comprises a mixture of oxygen-containing compounds of aluminum, copper, nickel and cobalt; and wherein the catalyst is present as one or more shaped catalyst particles selected from spheres, extrudates, pellets and other geometries, wherein the sphere or extrudate has a diameter of &#x3c;3 mm, the pellet has a height of &#x3c;3 mm, and the other geometries have an equivalent diameter L=1/a' of &#x3c;0.70 mm, where a&#x2032; is the external surface area per unit volume (mm/mm), as defined by where Ais the external surface area of the catalyst particle (mm) and Vis the volume of the catalyst particle (mm).
