In collaboration with LanzaTech we have developed a chemistry to generate p-xylene from ethanol. The innovation involves the conversion of ethanol derived acetaldehyde to p-methylbenzaldehyde over mixed oxide catalyst followed by the conversion to p-xylene via hydrogenolysis (ethanol → acetaldehyde → p-methyl benzaldehyde → p-xylene). Among aromatics, the production distribution contains only p-xylene, o-xylene and benzene. Typical p-xylene synthesis (both conventional and renewable) process contains range of aromatics (e.g. benzene, toluene, o-xylene, ethyl benzene, m-xylene, 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 renewable technologies. 1) The aromatic mixture to p-xylene separation/purification steps become simpler and cheaper 2) Enables to build a modular plant to meet the local renewable feedstock availability and reduces the feedstock transportation cost
