Examples
Embodiment 1
[0035] The aromatic hydrocarbon alkylation reaction was carried out according to the steps and conditions described in Comparative Example 2, but dimethyl ether was used instead of methanol as the alkylation reagent. The reaction evaluation results are listed in Table 1 for comparison.
[0036] Table 1
[0037]
Embodiment 2~5
[0039] The alkylation reaction was carried out according to the steps and conditions described in Example 1, but the catalyst regeneration conditions were adjusted. The specific regeneration conditions and reaction evaluation results are listed in Table 2 for comparison.
[0040] Table 2
[0041]
Embodiment 6~9
[0043] According to the steps and conditions described in Example 1, the aromatic hydrocarbon alkylation reaction was carried out, but the aromatic hydrocarbon feed was a mixture of benzene and toluene. The specific aromatic hydrocarbon feed ratio and reaction evaluation results were listed in Table 3 for comparison. The alkylation reagent was almost completely converted. , which will not be explained below.
