Latest Patents

Calvert holds a patent for the "Isomerization of aromatic compounds over ZSM-22 zeolite." This patent describes a process where a mixture of aromatic hydrocarbons, including xylenes, is isomerized in the presence of ZSM-22 zeolite. The process aims to produce a product stream where the proportion of para-xylene is substantially equal to the equilibrium ratio of the para-isomer. The isomerization is conducted at temperatures ranging from about 500°F to about 1100°F and pressures from about 0 to about 3000 psig. The process may also involve hydrogen and a catalyst containing about 0.005% to about 5.0% of a metal, such as platinum, palladium, or cobalt, based on total catalyst weight. This innovative approach enhances the efficiency and yield of para-xylene production.
