PROCESSO PER LA PREPARAZIONE DI DISTILLATI MEDI DA MISCELE H2/CO

摘要

Middle distillate hydrocarbons are produced from feed mixtures of carbon monoxide and hydrogen by contacting said feed at elevated temperature and pressure in a first stage with certain impregnated catalysts and contacting at least the middle distillate fraction of the product of the first stage in the presence of hyrogen with a catalyst containing at least one metal having hydrogenation activity supported on a porous carrier.
