PROCESS FOR THE PREPARATION OF HYDROCARBONS

摘要

The invention concerns a process for the preparation of hydrocarbons and generation of heat of carbon monoxide and hydrogen in the presence of a catalyst at elevated temperature and pressure in at least two stages which comprises: (i) introducing a gas comprising carbon monoxide and hydrogen int o a first reactor section comprising catalyst and introducing cooling fluidum into this first reactor section; (ii) allowing a part of the carbon monoxide to react catalytically in the first reactor section to hydrocarbons and wate r, at least part of the reaction heat being absorbed directly by the cooling fluidum; (iii) withdrawing from the reactor section a stream consisting of t he reaction product comprising the hydrocarbons, water, unconverted feed and cooling fluidum; (iv) cooling down at least a part of the withdrawn stream comprising cooling fluidum to generate heat; (v) optionally removing water from the withdrawn stream; (vi) repeating at least once steps i-v with the stream obtained in step v in further reactor section(s). The invention furth er relates to a reactor suitable for carrying out the above process.
