Selective alkylation of toluene with methanol to produce para-xylene
TL;DR: In this paper, a controlled reduction in the effective dimensions of the catalyst pore openings, and/or channels, along with deactivation of acidic surface sites, has been proposed as a mechanism for the selective production of p-xylene.
Journal ArticleDOI
Shape selective reactions with zeolite catalysts: III. Selectivity in xylene isomerization, toluene-methanol alkylation, and toluene disproportionation over ZSM-5 zeolite catalysts
TL;DR: In this article, data were presented for para-selective and nonselective formation of xylenes from alkylation of toluene with methanol and disproportionation over ZSM-5 class zeolite catalysts.
Journal ArticleDOI
Shape-selective reactions with zeolite catalysts: II. Selective disproportionation of toluene to produce benzene and p-Xylene
TL;DR: In this paper, a mechanism was proposed where oxides of these elements, present in the zeolites, reduce the dimensions of pore openings and channels sufficiently to favor formation and outward diffusion of p-xylene, the isomer with the smallest minimum dimension.

TL;DR: In this article, a process for the selective production of para-xylene by methylation of toluene in the presence of a catalyst comprising a crystalline aluminosilicate zeolite was described.
Patent
Extending catalyst life by treating with phosphorus and/or steam
TL;DR: In this article, a method for decreasing catalyst coking and extending the usable catalyst life by pre-treatment of the catalyst with steam and/or a phosphorus-containing compound was proposed.
