Patent

CA 2389079

This invention relates to a jet fuel blend comprising a major amount of a kerosine fraction boiling within the range of 140~ to 250 ~C and a minor amount of a naphtha fraction produced by the catalytic cracking of heavy gas oil which has a distillation range of T5 = 165 ~C to T95 = 210 ~C and an aromatics content of at least 50 % by volume such that the resultant jet fuel blend has a freezing point below that of the kerosine prior to blending. The blends of the present invention can achieve freezing points below -53.5 ~C.

L'invention concerne un mélange de carburéacteur qui renferme une grande quantité d'une fraction kérosène en ébullition à une température comprise entre 140· et 250 ·C et une plus faible quantité d'une fraction naphte produite par le craquage catalytique de gaz-oil lourd qui comporte une plage de distillation comprise entre T¿5?=165 ·C et T¿95?=210 ·C et une teneur en aromatiques d'au moins 50 % par volume, de façon que le carburéacteur ainsi produit ait un point de gel inférieur à celui du kérosène avant mélange. Les mélanges de la présente invention peuvent obtenir des points de gel inférieurs à 53 ·C.
