Description
本发明是关于烃油的精制方法，更具体地说，是合成烃油的吸附精制方法。The present invention relates to a refining method of hydrocarbon oil, more specifically, an adsorption refining method of synthetic hydrocarbon oil.
合成烃油具有优良的低温流动性，较高的粘度指数和闪点，较低的残炭、灰分和S、N杂质含量，因此，自三十年代部世以来，就在欧美和我国获得了广泛的应用。三十年代末，德国IG公司(POLiTZ)开发的用蜡裂解烯烃生产聚合油的方法(见Ind.Eng.Chem.，Vol42，NO.122428，1950年)是最早实现工业化的生产合成烃油的工艺路线。为了改进烯烃聚合油的色度和性能，该工艺用活性白土对聚合油进行吸附精制。由于合成烃油的溴值和不饱和度高，为防止精制时发生热氧化反应，该工艺采用了较低的精制温度(95℃)，精制时间较长(2小时)。Synthetic hydrocarbon oil has excellent low temperature fluidity, high viscosity index and flash point, low carbon residue, ash and S, N impurity content, therefore, since the 1930s, it has been widely used in Europe, America and my country Wide range of applications. At the end of the 1930s, the method developed by German IG company (POLiTZ) to produce polymerized oil by cracking olefins with wax (see Ind. Routing. In order to improve the color and performance of olefin polymerized oil, activated clay is used to adsorb and refine the polymerized oil in this process. Due to the high bromine value and unsaturation of synthetic hydrocarbon oil, in order to prevent thermal oxidation reaction during refining, this process adopts a lower refining temperature (95°C) and a longer refining time (2 hours).
中国是利用蜡裂解α烯烃生产合成烃油的重要国家，其工艺路线与IG公司的方法大体相同，但在聚合反应条件和吸附精制条件方面略有改进(见日本石油学会志Vol.19；NO.11897-905，1976年)。如，在聚合时大多采用AlCl3的催化剂，吸附精制采用活性白土-Ca(OH)2，精制温度略有提高，一般为110～130℃，精制时间0.5～1小时。利用该法精制可改善聚合油的色度，但效果仍不理想，其色度深于同等粘度级别的矿油基础油。China is an important country that utilizes wax cracking α-olefins to produce synthetic hydrocarbon oil. Its process route is roughly the same as that of IG Company, but there are slight improvements in polymerization reaction conditions and adsorption refining conditions (see Journal of the Petroleum Society of Japan Vol.19; NO .11897-905, 1976). For example, the catalyst of AlCl 3 is mostly used during polymerization, activated clay-Ca(OH) 2 is used for adsorption and purification, the refining temperature is slightly increased, generally 110-130°C, and the refining time is 0.5-1 hour. Refining by this method can improve the chromaticity of the polymerized oil, but the effect is still unsatisfactory, and its chromaticity is deeper than that of the mineral oil base oil of the same viscosity grade.
由于生产合成烃油时大多采用AlCl3络合催化剂，在聚合过程中，这类催化剂不可避免地生成了一些腐蚀金属和影响油品性能的有机氯化物，精制时应当除去，但目前尚无简便有效的脱除方法。Since AlCl3 complex catalysts are mostly used in the production of synthetic hydrocarbon oils, during the polymerization process, these catalysts inevitably generate some organic chlorides that corrode metals and affect the performance of oil products, which should be removed during refining, but there is currently no convenient effective removal method.
润滑油中的水分对油品的性能有着许多不利的影响，它可能造成油品的乳化、腐蚀，加速油品的衰败和添加剂的分解，还会影响油品的电性能。因此多数工业润滑油都必须尽可能地去除油中的水分。Moisture in lubricating oil has many adverse effects on the performance of the oil. It may cause emulsification and corrosion of the oil, accelerate the decay of the oil and the decomposition of additives, and also affect the electrical properties of the oil. Therefore, most industrial lubricants must remove as much water as possible from the oil.
润滑油中的轻馏份不仅影响油品的闪点，增大油品的挥发性，而且会加速油品在使用中的氧化变质，因此优良的润滑油基础油必须具有较窄的馏份范围。The light distillate in lubricating oil not only affects the flash point of the oil, increases the volatility of the oil, but also accelerates the oxidative deterioration of the oil in use, so an excellent lubricating oil base oil must have a narrow range of distillates .
本发明的目的在于克服现有技术精制效果差、精制时间长的缺陷，提供一种合成烃油的吸附精制方法，确切地说，是提供一种精制深度高，精制时间短，脱色效果好，同时还可脱除水、轻馏份及有机氯化物的合成烃油的吸附精制方法。The purpose of the present invention is to overcome the defects of poor refining effect and long refining time in the prior art, and provide a method for adsorption and refining of synthetic hydrocarbon oil. At the same time, it is also an adsorption refining method for synthetic hydrocarbon oil that can remove water, light fractions and organic chlorides.
本发明提供的合成烃油的吸附精制方法包括：将合成烃油和固体吸附剂混合，在缺氧条件下加热至100～250℃，恒温0～30分钟，降温至100℃以下，分离除去固体吸附剂。The adsorption refining method of synthetic hydrocarbon oil provided by the present invention comprises: mixing synthetic hydrocarbon oil and solid adsorbent, heating to 100-250°C under anaerobic conditions, keeping the temperature constant for 0-30 minutes, cooling to below 100°C, and separating and removing the solid Adsorbent.
所述合成烃油包括烯烃齐聚油，蜡裂解的α烯烃聚合油，以及α烯烃与苯烷基化的烷基苯合成油等。其中蜡裂解α烯烃可以是软蜡(一般含油量20～40％)或皂蜡(一般含油量3～5％)裂解的α烯烃。The synthetic hydrocarbon oil includes olefin oligomerized oil, α-olefin polymerized oil obtained by wax cracking, and alkylbenzene synthetic oil obtained by alkylating α-olefin and benzene. Wherein the wax-cracked α-olefin can be the α-olefin cracked by soft wax (generally 20-40% oil content) or soap wax (generally 3-5% oil content).
所述固体吸附剂为本领域通用的吸附剂，如白土、沸石、活性炭等，其中白土可以活化，也可以不活化；沸石可以是Y型沸石、丝光沸石、Ω沸石、γ沸石、毛沸石、ZSM系列沸石以及Beta沸石等，吸附剂的用量一般为合成烃油重量的1～12％，烃油粘度越大，色度越深，吸附剂的用量也就越大。The solid adsorbent is a general adsorbent in the art, such as clay, zeolite, activated carbon, etc., wherein the clay can be activated or not activated; the zeolite can be Y-type zeolite, mordenite, omega zeolite, gamma zeolite, erionite, For ZSM series zeolite and Beta zeolite, etc., the amount of adsorbent is generally 1-12% of the weight of synthetic hydrocarbon oil. The higher the viscosity of hydrocarbon oil and the deeper the color, the greater the amount of adsorbent.
所述缺氧条件可以是减压抽空，真空度为1～500mmHg，最好是1～350mmHg，真空度越高，精制效果越好。缺氧条件也可以是通入惰性气体，如CO2、氮气、氦气、氩气等与油中的组份不发生化学反应的气体，压力至少为1atm，最好是略大于1atm，如1～1.2atm，所用压力应保证系统处于稳定的惰性气体环境。用减压抽空方法获得的精制效果更佳。精制温度为100～250℃，升温速度为本领域常用的升温速度，当温度达到精制温度时，可立即降温，也可以恒温一段时间，一般来说精制温度低、升温速度慢，恒温的时间宜略长，如＜0～30分钟，当然恒温时间超过30分钟也是可以的，只是精制效果已不再有显著变化。The anoxic condition can be decompression and evacuation, the degree of vacuum is 1-500 mmHg, preferably 1-350 mmHg, the higher the degree of vacuum, the better the refining effect. Anoxic conditions can also be fed inert gas, such as CO 2 , nitrogen, helium, argon and other gases that do not chemically react with the components in the oil, and the pressure is at least 1 atm, preferably slightly greater than 1 atm, such as 1 ~1.2atm, the pressure used should ensure that the system is in a stable inert gas environment. The refining effect obtained by decompression and evacuation method is better. The refining temperature is 100-250°C, and the heating rate is the usual heating rate in this field. When the temperature reaches the refining temperature, the temperature can be lowered immediately or kept at a constant temperature for a period of time. Generally speaking, the refining temperature is low and the heating rate is slow, and the time for constant temperature is appropriate. Slightly longer, such as <0 to 30 minutes, of course, it is also possible to keep the constant temperature for more than 30 minutes, but the refining effect has no significant change.
本发明提供的合成烃油的吸附精制方法由于采用了缺氧条件，因而具有如下优点：The adsorption and refining method of synthetic hydrocarbon oil provided by the invention has the following advantages owing to the adoption of anoxic conditions:
(1)精制时间短，只需30分钟甚至时间更短，精制深度高，脱色效果明显。如，利用该法可使ISO VG68合成烃油的色度由4.5级降至0.5级。(1) The refining time is short, only 30 minutes or less, the refining depth is high, and the decolorization effect is obvious. For example, using this method, the chromaticity of ISO VG68 synthetic hydrocarbon oil can be reduced from 4.5 to 0.5.
(2)可脱除水、轻馏份及有机氯化物。如，利用该法可使合成烃油的有机氯化物含量从205ppm降至8.4ppm，水分从320ppm降至30ppm，闪点从174℃提高至206℃。(2) It can remove water, light fractions and organic chlorides. For example, using this method, the organic chloride content of synthetic hydrocarbon oil can be reduced from 205ppm to 8.4ppm, the water content can be reduced from 320ppm to 30ppm, and the flash point can be increased from 174°C to 206°C.
另外，将本发明提供的方法与现有技术相结合，加入适量Ca(OH)2，可更有效地中和油中的酸性物质，例如，可使酸值从0.5mgKOH/g降至0.02mgKOH/g、In addition, combining the method provided by the present invention with the existing technology, adding an appropriate amount of Ca(OH) 2 can more effectively neutralize the acidic substances in the oil, for example, the acid value can be reduced from 0.5mgKOH/g to 0.02mgKOH /g,
