Production of benzene, toluene and xylenes

Since the BTX-aromatics benzene, toluene and xylene are co-generated, alongside other aromatics and non-aromatics during coal conversion and petroleum refining, their concurrent recovery is described jointly in this chapter.

Isomerization and transalkylation reactions to redistribute methyl groups on aromatic molecules are important processes in the production of benzene, toluene and xylenes (BTX). In particular, the production of para-xylene is preferred. The interconversion of C8 aromatics is covered in much greater depth in Section 14.3.

Tables 4.14,4.15 and 4.16 show the regional distribution of the production of benzene, toluene and xylene.
