PROCESSO PER LA PREPARAZIONE DI IDROCARBURI E IDROCARBURI IN TAL MODO OTTENUTI

摘要

Two-stage process for the preparation of hydrocarbons from syngas with an H2/CO mol. ratio between 1.0 and 2.0, in which the syngas is contacted in a first stage with a bi- or trifunctional catalyst comprising a crystalline silicate with ZSM-5 structure followed by contacting at least the C<{>2 fraction of the first stage product in a second stage with a mono- or bifunctional catalyst comprising a Ni, Co or Ru Fischer-Tropsch function. In this way an economical very attractive process combination is achieved for the production of both aromatics and paraffins.
