“…This reaction mechanism was suggested to explain the formation of aromatic and alicyclic hydrocarbons in the Fischer-Tropsch synthesis on iron Cady et al, 1953). Similarly, adsorbed species with a 5-carbon ring can also be formed as intermediates in isomerization reactions, as discussed later in this section.…”

“…The product distributions of Tests 1 and 3 given in Table I indicate that the proportion of alkenes is small at 325°C compared to 355°C while the amount of branched alkanes decreases from 10.7 mole % in Test 3 to 7.0%. Cady et al (1953) characterized the products from CO hydrogenation on Fe in a fluidized bed reactor operated at 315°C and 18 atm with a feed ratio of 2:l for H2/C0. Paraffins accounted for 12.8 volume % of all C, hydrocarbons and 16.5% of the CI4's while the proportion of olefins dropped from 86.9% to 63.6%.…”

The hydrogenolysis of normal hexadecane was studied over iron at 325" and 355°C. As expected with iron catalysts, the main product was methane, but the selectivities for intermediate alkanes were moderately large, probably due to the length of the carbon chain. Furthermore, gas chromatography -mass spectrometry analysis of the heavier products indicated the presence of alkylbenzenes, alkenes and branched alkanes which accounted for about 20 mole % of the CY-Ct3 hydrocarbons. When 5.7 mole % of carbon monoxide was added to the feed, hydrogenolysis reactions were inhibited and products similar to those in the Fischer-Tropsch synthesis were found. Therefore, CO acts like a poison for the hydrogenolysis of hydrocarbons. L'hydrogknolyse de I'hexadkcane normal en prksence d'un catalyseur au fer a ktC Ctudike ? i 325 et 355°C. Comme on pouvait s'y attendre avec un catalyseur au fer, le principal produit obtenu est le mkthane mais la sklectivite pour les alcanes normaux de poids rnolkculaire plus klevk est relativement grande, probablement cause de la longueur de la chaine de carbone de I'hexadkcane. De plus, I'analyse des produits de poids molkculaire klevt, par chromatographie en phase gazeuse et par spectromktrie de masse, indique la prksence d'alkylbenztnes, d'alches et d'alcanes ramifies qui comptent ensemble pour environ 20% en mole des hydrocarbures ayant de 9 13 atomes de carbone.

A classification of fischer–tropsch synthesis product distributions

1984

Two types of product distributions in Fischer–Tropsch synthesis have been observed; the “classical” distribution where successive carbon numbers contain homologous groups of compounds and the “non‐classical” where the product spectrum deviates from the above picture. It is proposed that the non‐classical distributions arise on bifunctional catalysts on which primary synthesis products are rapidly converted to isomeric secondary products.
