Abstract

Un proceso para la síntesis exotérmica heterogénea de formaldehido, en especial en un reactor del tipo que consiste en una pluralidad de estratoscatalíticos conectados en serie, comprendiendo dicho proceso las etapas de: alimentar reactivosgaseosos consistentes en metanol y oxígeno en exceso adicho reactor; hacer que dichos reactivos gaseosos fluyan a través de dichos estratos catalíticos adiabáticos para someter el metanol a una oxidaciónparcial; caracterizado porque el metanol allimentado al reactor de la síntesis se distribuye en por los menos dos porciones, cada una de las cuales alimenta alos respectivos estratos catalíticos distintos. La invención también presenta el reactor para la síntesis exotérmica heterogénea deformaldehido que constade un gabinete externo vertical (cilíndrico) y una pluralidad de estratos catalíticos adiabáticos tal que el distribuidor del flujo que contiene elmetanol está soportado por lo menos por dos estratos catalíticos consecuttivos.
