Abstract

Un proceso para la síntesis exotérmica heterogénea de formaldehído, en particular en un reactor (7) del tipo que comprende una pluralidad de lechos catalíticos adiabáticos (11a-11e) conectados en serie, proporciona el paso de alimentar el reactor el metanol necesario para la síntesis, distribuido en cuando menos dos porciones, cada una alimentada hacia lechos catalíticos distintos respectivos (11a- 11e).
