Abstract
This present disclosure relates to processes and apparatuses for toluene and benzene methylation in an aromatics complex for producing paraxylene. More specifically, the present disclosure relates to processes and apparatuses for toluene and benzene methylation within an aromatics complex for producing paraxylene wherein an embodiment uses a reactor having a refractory comprising a low iron content refractory.
Claims18
A process for alkylating an aromatic hydrocarbon reactant with an alkylating reagent comprising methanol to produce an alkylated aromatic product, comprising:
- introducing the aromatic hydrocarbon into a reactor having an inner refractory lining having a low iron content;
- and
- recovering the alkylate aromatic product, produced by reaction of the aromatic reactant and the alkylating reagent, from the reactor.
An apparatus for alkylating an aromatic hydrocarbon reactant with an alkylating reagent comprising methanol to produce an alkylated aromatic product, comprising:
- a line comprising the aromatic hydrocarbon in upstream communication with a reactor having an inner refractory lining;
- and
- a line in downstream communication with the reactor comprising the alkylate aromatic product, produced by reaction of the aromatic reactant and the alkylating reagent, from the reactor.
