Abstract
Disclosed are a fluidized bed gas distributor and a fluidized bed reactor, the fluidized bed reactor comprising a first distributor () and a second distributor (), wherein the first distributor () is located at the bottom of a fluidized bed, and second distributor () is located downstream of a gas from the first distributor (). Also disclosed is a method for producing a para-xylene and co-producing light olefins, the method comprising the following steps: material stream A enters a reaction zone () of a fluidized bed reactor from a first gas distributor (); material stream B enters the reaction zone () of the fluidized bed reactor from a second gas distributor (); and the reactants are brought into contact with a catalyst in the reaction zone () to generate a gas phase stream comprising para-xylene and light olefins.
