A process to prepare paraffins and waxes is provided, the process comprising: subjecting a Fischer-Tropsch product stream comprising paraffins having from 10 to 300 carbon atoms to a hydrogenation step, thereby obtaining a hydrogenated Fischer-Tropsch product stream comprising 10 to 300 carbon atoms; separating the hydrogenated Fischer-Tropsch product stream, thereby obtaining at least a fraction comprising 10 to 17 carbon atoms and a fraction comprising 18 to 300 carbon atoms; separating the fraction comprising 18 to 300 carbon atoms, thereby obtaining one or more first light waxes having a congealing point in the range of 30 to 75&#xb0; C. and a second heavy wax having a congealing point in the range of 75 to 120&#xb0; C.; and hydrofinishing one or more wax fractions having a congealing point in the range of 30 to 75&#xb0; C. thereby obtaining one or more hydrofinished wax fractions having a congealing point in the range of 30 to 75&#xb0; C.

Process to prepare paraffin wax

The present invention provides a paraffin wax having a congealing point according to ASTM D938 of at least 100&#xb0; C. and a Saybolt colour according to ASTM D156 of at least 25 cm.
