Definitions

  • the invention is directed to a method to increase the cetane number of a gas oil product based on a petroleum derived gas oil by adding to the petroleum derived gas oil an amount of a Fischer-Tropsch derived gas oil.
  • petroleum derived gas oils have generally a lower cetane number than gas oils, derived from a Fischer-Tropsch process.
  • Fischer-Tropsch derived gas oil A problem with Fischer-Tropsch derived gas oil is that they are not widely available and that the cost of preparing such gas oils is believed to be higher than the cost of preparing petroleum derived gas oil for the foreseeable future. There is thus a continuous drive to minimize the amount of Fischer-Tropsch derived gas oil in such a blend while meeting the different final product specifications.
  • Fischer-Tropsch derived gas oil is less than the amount which would be added if linear blending is assumed.
  • the fraction x will be a value between 0 and 1 and preferably greater than 0.02.
  • the invention is in particular directed to blends wherein the fraction x of Fischer-Tropsch derived gas oil is less than 0.7 and more preferably less than 0.5 and most preferably between 0.05 and 0.3.
  • A is the cetane number of the petroleum derived gas oil and B the cetane number of the Fischer-Tropsch derived gas oil.
  • the cetane number of the petroleum derived gas oil and the Fischer-Tropsch derived gas oil as used in the method according the invention may be measured according the normal ASTM D613 method.
  • a more preferred method is by measuring the cetane number by near infrared spectroscopy (NIR) as for example described in detail in US-A-5349188. Such measurements will include the use of a correlation between the measured spectrum and the actual cetane number of the sample.
  • NIR near infrared spectroscopy
  • the underlying model is made by correlating the cetane number according to ASTM D613 of a wide variety of petroleum derived samples, Fischer-Tropsch derived gas oil samples and/or their blends with their near infrared spectral data.
  • the method according to the invention is embedded in an automated process control of the blending operation in for example a refinery environment.
  • a process control may use so-called quality estimators which will provide, by making use of a model, a real time prediction of the cetane number of the resulting blend from readily available raw process measurements, such as for example the cetane numbers as measured by NIR and the volumetric flows.
  • quality estimators is calibrated on-line by making use of for example the method described in detail in WO-A-0206905.
  • the Fischer-Tropsch derived gas oil may be any gas oil, which is prepared from the synthesis product of a Fischer-Tropsch synthesis.
  • the gas oil product may be obtained by fractionation of such a Fischer-Tropsch synthesis product or obtained from a hydroconverted (hydrocracking/hydroisomerisation) Fischer-Tropsch synthesis product.

  • the Fischer-Tropsch derived gas oil will consist of at least 90 wt%, more preferably at least 95 wt% of iso and linear paraffins.
  • the weight ratio of iso-paraffins to normal paraffins will suitably be greater than 0.3. This ratio may be up to 12. Suitably this ratio is between 2 and 6.
  • the actual value for this ratio will be determined, in part, by the hydroconversion process used to prepare the Fischer-Tropsch derived gas oil from the Fischer-Tropsch synthesis product. Some cyclic-paraffins may be present.
  • the Fischer-Tropsch derived gas oil has essentially zero content of sulphur and nitrogen (or amounts which are no longer detectable) .
  • the Fischer-Tropsch derived gas oil will suitably have a distillation curve which will for its majority be within the typical gas oil range: between about 150 and 400 °C.
