Abstract:
This is a three stage process: prefractionation, hydrotreating, and
separation of n-paraffins. Kerosene in the l60-28S'C boiling range is
prefractionated to give a stream in the desired range of carbon numbers.
This stream is passed through a hydrotreater to remove sulphur. Separation
of n-paraffin is carried out in the vapour phase at l7SoC. At least three
adsorbers are used, one adsorbing, one purifying and one desorbing using
hexane as a desorbent.
