Vynález sa týká použitia polyetylénu, po-dielu rozpustného v rozpúšťadle iniciátora,ktorý je vedlajším produktem pri výroběpolyetylénu vysokotlakovým spósobom, akodepresantu do ropných frakcií.The present invention relates to the use of polyethylene, a solvent-soluble part of the initiator, which is a by-product of the high-pressure production of polyethylene and to the oil fractions.

Na znižovanie teploty tuhnutia ropnýchproduktov sa používajú rožne látky, ktorémodifikujú kryštalizáciu parafínu a tým zlep-šujú túto závažnú charakteristiku. Spósobujú,že parafín sa nevylučuje vo formě splstenejmriežky, ktorá znehybňuje olej, ale ako kom-paktně kryštály, ktoré plávajú v oleji. Akoznižovanie bodu tuhnutia sa používajú na-příklad kondenzačně splodiny chlórovanéhoparafínu s naftalénom alebo s fenolom, poly-akryláty a polymetakryláty vyšších mastnýchalfcoholov, polyvinyloleáty a v poslednom ob-dobí aj kopolyméry etylénu a vinylacetátu.In order to reduce the freezing point of petroleum products, grits are used which modify the crystallization of the paraffin and thus improve this significant characteristic. They cause paraffin to not be deposited in the form of a braided mesh that immobilizes the oil, but as compact crystals that float in oil. Lowering the freezing point, for example, is the condensation product of chlorinated paraffin with naphthalene or phenol, polyacrylates and polymethacrylates of higher fatty alcohols, polyvinyl oleate and, more recently, ethylene / vinyl acetate copolymers.

Teplotu tuhnutia tiež móžu znižovať ajropné živice, asfaltény a ťažké polyaroma-tické uhlovodíky, ktoré sa používajú ako de-presanty pre 1’ahké vykurovacie oleje, tietovšak ako prídavok vplývajú na zafarbenieupravovanej frakcie. Naviac tieto nezlepšujú filtrovatelnosť motorových náft za nízkých 1 » · teplot.The freezing point can also be reduced by araropic resins, asphaltenes, and heavy polyaromatic hydrocarbons, which are used as desantiants for light fuel oils, but also add to the color treated fraction. In addition, these do not improve the filterability of diesel fuel at low temperatures.

Nedostatky tohoto druhu sú odstraněné vynálezom, ktorého podstatou je použitiepolyetylénu, podielu rozpustného v rozpúš-ťadle iniciátora, ktorý je vedlajším produk-tem pri výrobě polyetylénu vysokotlakýmspósobom, ako depresantu do ropných frakcií.The drawbacks of this kind are eliminated by the invention, which is based on the use of polyethylene, a solvent-soluble portion of the initiator, which is a by-product of high-pressure polyethylene production as a depressant to petroleum fractions.

Prítomnosť depresantu podlá vynálezu saprejavuje tým spósobom, že ovplyvňuje rastkryštálov parafínu, krystalizuj úceho v róz-nych kryštálových formách. Látka je vedl’aj-ším produktem — odpadom pri výrobě nízko-hustotného polyetylénu a jej přísada nefarbíropná frakciu. V motorových naftách zvyšujecetánové číslo o 1 až 2 jednotky a zlepšujeich filtrovatelnosť. Malé zvýšenie viskozit-ného indexu sa pozoruje aj pri jeho aplikáciido olejov. Vynález a jeho účinky sú uvedenév príkladoch prevedenia bez toho, aby sa ibana tieto vztahovali. Příklad 1The presence of a depressant according to the invention thus shows that it affects paraffin crystals crystallizing in different crystal forms. The substance is a by-product of low-density polyethylene waste and its non-pharropic fraction additive. Increase the ethane number by 1 to 2 units in diesel and improve filterability. A small increase in viscosity index is also observed in its application of oils. The invention and its effects are exemplified without the iban being related thereto. Example 1

Do motorovej nafty sa přidalo 0,01 až0,15% hmotnostných polyetylénu, podielurozpustného v rozpúšťadle iniciátora, ktorýje vedlajším produktem pri výrobě polyety-lénu vysokotlakým spósobom a sledovala sateplota vylučovania parafínu, filtrovatelnosť 2162860.01 to 0.15% by weight of polyethylene, insoluble in the initiator solvent, was added to the diesel fuel, which is a by-product of high-pressure polyethylene production and monitored the temperature of the paraffin deposition, filterability 216286
