Abstract
The process for producing alkylated aromatic compounds includes feeding raw materials including an aromatic compound, a ketone and hydrogen in a gas-liquid downward concurrent flow mode to a fixed-bed reactor packed with a catalyst thereby to produce an alkylated aromatic compound, wherein the catalyst includes a solid acid component and a metal component, the catalyst is loaded in the fixed-bed reactor such that the catalyst forms a catalyst layer, and the reaction gas flow rate defined by Equation (1) below is not less than 0.05 at an entrance of a layer containing the solid acid: ρg·ug·[ρair·ρwater/(ρg·ρl)]1/2 (kgm−2s−1).
Claims20
A process for producing alkylated aromatic compounds comprising feeding raw materials including an aromatic compound, a ketone and hydrogen in a gas-liquid downward concurrent flow mode to a fixed-bed reactor packed with a catalyst thereby to produce an alkylated aromatic compound, wherein
- the catalyst comprises a solid acid component and a metal component comprising at least one metal selected from the group consisting of copper, nickel, cobalt and rhenium,
- the catalyst is loaded in the fixed-bed reactor such that the catalyst forms a catalyst layer having a single layer or a plurality of layers, and
- the reaction gas flow rate defined by Equation (1) below is not less than 0.05 at an entrance of a layer containing the solid acid which layer is included in the catalyst layer:
- ρg·ug·[ρair·ρwater/(ρg·ρl)]1/2 (kgm−2s−1) (1)
- wherein ρg is the density of the reaction gas, ρl is the density of the reaction liquid, ρair is the gas density of air, ρwater is the gas density of water, and ug is the superficial velocity of the reaction gas.
