How is fatty alcohol made, and why has direct fatty acid hydrogenation become the dominant route?
The shift to one-step hydrogenation is really a cost story. Shorter flowsheets mean lower energy and capex per ton, which matters when feedstock is the dominant cost. But copper-chromium catalysts carry environmental baggage, so watch whether copper-zinc-aluminium systems gain share under tighter discharge rules. Catalyst choice may become a compliance issue, not just an economic one.
