Abstract:
The invention relates to a shell catalyst that can be obtained from a catalyst precursor comprising, (a) a support body, (b) a shell containing (i) a catalytically active multi-metal oxide containing molybdenum and at least one other metal, represented by general formula (I) Mo12Bia Crb X1 cFedX2 eX3 f0y (I), wherein X1 = Co and/or Ni, X2 = Si and/or AI, X3 = Li, Na, K, Cs and/or Rb, 0,2
Abstract:
The invention relates to a shell catalyst comprising: (a) a support body, (b) a first layer containing a molybdenum oxide or a precursor compound forming molybdenum oxide, (c) a second layer containing a multi-metal oxide containing a molybdenum and at least one other metal. Preferably, the molybdenum oxide of the first layer is MoO3 and the multi-metal oxide of the second layer is a multi-metal oxide represented by general formula (Il): Mo12BiaCrbX1 cFedX2 eX3 fOy.
Abstract:
The present invention relates to a porous inorganic body comprising pores A having a pore size SA in the range of from 0.005 to 20 micrometer and a total pore volume VA, and comprising pores B having a pore size SB in the range of from more than 20 to 1000 micrometer and a total pore volume VB, wherein the total pore volume of the pores having a pore size in the range of from 0.005 to 1000 micrometer is VC and wherein the ratio RA = VA / VC is in the range of from 0.3 to 0.7 as determined via mercury intrusion porosimetry.
