Latest Patents
Xiawan Yang holds a patent for a method of catalyst selectivation. This patent describes a process where catalysts are modified by depositing an agent derived from organometallic compounds. This modification allows for increased selectivity to para-substituted alkyl benzenes, such as para-xylene (PX). The process involves reacting aromatic compounds like toluene and/or benzene with a methylating agent derived from hydrogen and carbon monoxide, carbon dioxide, or methanol. Using these selectivated catalysts, para-substituted alkyl benzenes can be recovered with a selectivity of 80% or greater, which is significantly better than the equilibrium concentration of 24%. Xiawan Yang has 1 patent to his name.
