We have developed a chemistry to generate p-xylene from ethanol. Theinnovation involves the conversion of ethanol derived acetaldehyde to p-methylbenzaldehyde overmixed oxide catalyst followed by the conversion to p-xylene via hydrogenolysis (ethanol →acetaldehyde → p-methyl benzaldehyde → p-xylene). Among aromatics, the production distributioncontains only p-xylene, o-xylene and benzene. Typical p-xylene synthesis (both conventional andrenewable) process contains range of aromatics (e.g. benzene, toluene, o-xylene, ethyl benzene, mxylene,p-xylene etc.) that needs to be purified via the expensive separation process.The simple aromatic stream provides to major advantages over the conventional and other renewabletechnologies.1) The aromatic mixture to p-xylene separation/purification steps become simpler and cheaper2) Enables to build a modular plant to meet the local renewable feedstock availability and reduces thefeedstock transportation cost
