Abstract

The silver method and ferro-molybdenum method for producing formaldehyde by air oxidation of methanol were summarized and compared.Silver method was employed as the main technology of formaldehyde production in China for its maturity.Ferro-molybdenum method was more suitable for the planning and development of formaldehyde industry for its low methanol consumption,high formaldehyde yield,long catalyst life and good economic benefit.Nevertheless,domestic technology of ferro-molybdenum method was not mature.The research progresses of silver,ferro-molybdenum and vanadium catalysts were reviewed.Silver catalyst was difficult to be improved greatly.Ferro-molybdenum was researched as a hotspot,and vanadium catalyst was still far away from industrial application.Further study on reaction mechanism for performance improvement of ferro-molybdenum catalyst was proposed as an important subject of methanol oxidation to formaldehyde.The development of ferro-molybdenum catalyst which was more compatible with the existing silver method process was suggested as the main research direction of formaldehyde production technology in the future.
