Description
Yi Yang and a large team test a neodymium promoter on iron-based catalysts for high-temperature Fischer-Tropsch synthesis of light olefins. The process runs hot, converting gas into short-chain products on precipitated iron catalysts. Their 2026 series builds catalysts with six dose grades of the rare earth element, plus two variants with sodium as a partner promoter. Structure, surface, and adsorption measurements track what the dose does to the catalyst.
A low dose shrinks particle size, grows surface area, and makes the surface more basic. Electron density crowds the iron, carbon monoxide splits more readily, and the active carbide phase grows, which lifts synthesis activity. Past an optimal dose, neodymium coats the surface, particles clump and grow, and performance falls. With sodium as partner, the best catalyst hit a yield of 412.1 units, past both single promoters alone.
