    Notizen: Abstract Syngas reaction mechanism studies on cobalt based catalysts suggested that the CO dissociation step and the (alcohol and/or hydrocarbon) chain growth can be well mimicked by CO disproportionation and temperature programmed desorption (TPD) of acetaldehyde. Correlation between C2+ hydrocarbon selectivity and CO disproportionation on the one hand, C2+ alcohol selectivity and TPD after acetaldehyde adsorption on the other hand could be evidenced.

    Influence of the hydrocarbons distribution on the heat produced during Fischer-Tropsch synthesis (1995)
    Springer
    Topics in catalysis 2 (1995), S. 301-311

    ISSN: 1572-9028
    Schlagwort(e): Fischer-Tropsch ; heat of reaction ; ASF distribution ; paraffin condensation ; water condensation

    Thema: Chemie und Pharmazie
    Notizen: Abstract The heat produced during Fischer-Tropsch synthesis has been calculated, considering a base case in which a typical Anderson-Schulz-Flory (ASF) distribution is followed by the paraffinic hydrocarbons produced. An equation has been obtained, which allows us to calculate the enthalpy of reaction, using the probability of chain growth as the variable. The effect of a deviation from the ASF distribution has been considered, through the example of a higher methane selectivity than in the base case. The correction due to the condensation of higher hydrocarbons has also been evaluated. In order to be able to perform energy balance calculations, the physical state of water at the reactor outlet has been checked.
