Superhigh-molecular weight polyolefin used as additive improving flowability of cold liquids

FIELD: polymer production. SUBSTANCE: invention relates to superhigh-molecular weight copolymer constituted by an α-olefin monomer with carbon chain length 4 to 9 carbon atoms and another comonomer, which is α-olefin with carbon chain length 2 to 20 carbon atoms or containing vinylaromatic monomer. Copolymer has molecular mass above 1000000 and no more than 25 mol % monomers with carbon chain length 12 carbon atoms or more. Copolymer of invention is completely dissoluble in heavy aromatic hydrocarbons at low temperatures such as 0°C. Another advantage of the copolymer consists in that it can be transported either in stable suspension or can be preliminarily dissolved in small amount of heavy hydrocarbon. Suspension of polymer lowering resistance of a medium is stable so allowing longer storage time and thereby enabling agreement between consumer's demand and delivery time. Secondary agglomeration of polymers leading to lower resistance of medium is considerably reduced ensuring easier processing in the production process.

Improved stability of hydrocarbons containing asphaltenes

Heavy fuel oils or residual fuel oils can be stabilized with magnesium overbased compounds such as magnesium overbased carboxylates. It was surprisingly discovered that adding magnesium overbased carboxylates to the residual fuel oils shortly after thermal cracking gave much better results than can be achieved after the application of the carboxylates to the fuel oil after storage. Further, compounds containing at least about 21 wt% magnesium also give better results than compounds with 18 wt% or less, in one non­ limiting embodiment. Magnesium overbased compounds can also be added to coker feedstocks to reduce coker furnace fouling. Treatment with the methods of this invention reduces asphaltene deposits and sludges.

The present invention provides a fuel additive for heavy oil in the form of a composition comprising an oil soluble metallic compound, an oxygen supplier, a dispersant, a lubricant, a nonionic surfactant, and a detergent. Addition of a small amount (0.025%) of the fuel additive of the present invention to the heavy oil can reduce the generation of particulate matter (PM), residual carbon, nitrogen oxides and the like upon combustion. In addition, when a small amount (0.025%) of the fuel additive of the present invention is added to the heavy oil, the maximum combustion pressure during combustion is increased while the exhaust temperature is lowered, thereby improving the combustion efficiency. Therefore, the fuel additive of the present invention is very useful for a large-sized boiler using heavy oil as a fuel, particularly a large-sized diesel engine.

A fuel composition containing an organic molybdenum complex

석유 모터 오일의 산화적 안정성은 연료에 (a) 디올, 디아미노 또는 아미노 알콜 화합물 및 (b) 착체의 중량을 기준으로 하는 약 2.0 내지 20.0%의 몰리브덴을 제공하기에 충분한 량의 몰리브덴 원을 반응시켜 제조된 유효량의 헤테로시클릭 몰리브덴 착체를 첨가함으로써 개선된다.

Synergetic antimicrobial composition

Изобретение относится к биоцидам. Синергетическая противомикробная композиция содержит: (a) гидроксиметилзамещенное соединение фосфора, представляющее собой соли тетракис(гидроксиметил)фосфония, и (б) второй биоцид, выбранный из группы, включающий (1) гексагидро-1,3,5-трис(2-гидроксиэтил)-s-триазин, (2) 2,6-диметил-1,3-диоксан-4-илацетат и (3) орто-фенилфенол или его соли щелочных металлов или соли аммония. Массовое соотношение гидроксиметилзамещенное соединение фосфора/гексагидро-1,3,5-трис(2-гидроксиэтил)-s-триазин составляет от 15:1 до 1:15. Массовое соотношение гидроксиметилзамещенное соединение фосфора/2,6-диметил-1,3-диоксан-4-илацетат составляет от 15:1 до 1:15. Массовое соотношение гидроксиметилзамещенное соединение фосфора/орто-фенилфенол или его соли щелочных металлов или соли аммония составляет от 15:1 до 1:5. Изобретение позволяет повысить эффективность композиции. 6 з.п. ф-лы, 6 табл., 6 пр.
