Definitions
- the higher boiling fraction as obtained after isolation of propylene and possible other low boiling compounds from the cracked effluent is preferably recycled to the one or more fixed beds.
- the high boiling fraction is contacted in admixture with the hydrocarbon feed with the heterogeneous cracking catalyst.
- the higher boiling fraction is first subjected to an isomerization step before being recycled to the one or more fixed beds. It has been found that the propylene yield may increase when such an isomerisation step is performed. Isomerisation of especially the normal pentanes and normal hexanes to their branched isomers has been found to increase the propylene yield.
- a suitable extraction process is an extractive distillation using one of the above described solvents and suitably sulfolane, N-formyl morpholine or N- methyl pyrrolidone, optionally in combination with a suitable co-solvent.
- a packed bed reactor was provided consisting of the MFI catalyst obtained in Example 1.
- a naphtha having a GC RON of 91.2 with 90% boiling point at 182°C consisting of 35 wt% paraffins, 12 wt% naphthenes, 31 wt% olefins and 22 wt% aromatics and 1.4 wt% normal pentane and 10.1 wt% iso-pentane was fed to the reactor at 1.4 g/min in 50 ml/min nitrogen at 500 °C.
- the WHSV was 57 h-1.
- the pressure at the reactor effluent was atmospheric.
- the cracked effluent was analysed and the results presented as (in weight percentages) are provided in Table 1.

Abstract
L'invention concerne un procédé de préparation de propylène à partir d'une charge d'alimentation d'hydrocarbures comprenant du pentane par la mise en contact de la charge d'alimentation d'hydrocarbures avec un catalyseur de craquage hétérogène tel que présent dans un ou plusieurs lits fixes, ce qui permet d'obtenir un effluent craqué. Le catalyseur hétérogène comprend un composant matriciel et un tamis moléculaire comprenant une structure d'alumine, une structure de silice et une structure de métal choisi dans le groupe constitué par Zn, Fe, Ce, La, Y, Ga et/ou Zr. Le propylène est isolé de l'effluent craqué.
