Several kinds of nitrile rubbers having different primary physical properties and different content of acrylonitrile and vulcanizing agent as well as different state of curing were used in test.The compatibility of nitrile rubbers having different composition and physical properties with jet fuels processed by various processing method was examined.The test results showed that the compatibility of jet fuels with the rubbers was not only related to the processing of jet fuels,but also to the composition and the process technology of rubbers.The compatibility of the rubbers with jet fuels processed by non hydrogenation process was better than those by hydroprocessing(especially by hydrocracking).The original physical properties of rubber are not the decisive factor relating to the compatibility.The ability of rubber resisting the peroxide attack is a main factor affecting the compatibility.The amount and composition of the extracts formed in jet fuels depend on the composition and also the production process of rubber.The combined effects on compatibility caused by various extracts from different kinds of rubber will be positive or negative.Although the original strength of rubber with sulfur as vulcanizer is lower than that with peroxide as vulcanizer,the compatibility of the former with jet fuels is much better than that of the latter.

采用几种具有不同初始物理性能及不同丙烯腈含量、不同硫化剂和硫化程度的丁腈橡胶 ,考察了其配方和物理性能对采用不同工艺条件生产的喷气燃料的相容性。结果表明 ,喷气燃料与橡胶的相容性不仅与喷气燃料的加工工艺有关 ,而且与橡胶的组成及其制备工艺有关。采用非加氢工艺生产的喷气燃料与橡胶的相容性好于采用加氢工艺 (特别是加氢裂化工艺 )生产的喷气燃料。橡胶材料的初始力学性能的好坏并不完全决定其与喷气燃料相容性的好坏 ,橡胶材料的耐过氧化物侵蚀能力才是影响相容性好坏的主要因素。橡胶的组成和其制备工艺决定了橡胶在喷气燃料中萃取物的数量和组成 ,不同萃取物的综合作用给相容性带来不同程度的影响。用硫作硫化剂的橡胶虽然原始强度低于用过氧化物作硫化剂的橡胶 ,但前者与喷气燃料的相容性却远好于后者。

production of super-low sulfur and emission-free fuelsis the general development trend in clean fuels in the worldtoday. With clean gasoline, the trend is the production offuels low in sulfur, benzene, aromatic hydrocarbons andolefins. With automotive diesel, the trend is seekingreduction of sulfur and aromatic hydrocarbons. The Cetanenumber, in particular, should be further raised whilepalycyclic aromatic content is reduced. The proportion ofcatalytic and cracking gasoline with high olefin content ingasoline is too high in China. Therefore, it is of greaturgency that the refineries adjust the technological structureof gasoline production, lower the sulfur content of gasolineand improve the hydrocarbon composition of their products.Since the proportion of poor-quality vehicle diesel fuel inChina is comparatively high, it is necessary to appropriatelydevelop the technology for deep desulfurization and thelowering of aromatic hydrocarbons in diesel to boost thegeneral quality level of automotive diesel. With moreimported sour crude being processed and the environmentalrequirements becoming stricter in China, the production ofclean fuels will inevitably be accelerated, with hydrogenationbecoming the key technology in oil refining. The variouscombined technology, centered on catalytic and crackingtechniques, together with the technologies for producingmore light olefin and the synthetic technologies for olefinupgrading, will experience further development.Development of various non-hydrogenation technologieswill be also put on the agenda. It is necessary to appropriatelyenlarge the single-refinery and single-unit scale in order to27P..promote optimization and comprehensive utilization ofresources and boost the overall performance of refineries.Residue oil deep processing and refining-petrochemicalintegration will continue as a general trend in China’s oilrefining industry .

生产超低硫、零排放燃料是世界燃油清洁化发展的总趋势。清洁汽油的发展趋势是低硫、低苯、低芳烃和低烯烃化,车用清洁柴油的发展趋势则是在降低硫、芳烃,尤其是降低多环芳烃含量的同时,进一步提高十六烷值。中国车用汽油构成中高烯烃含量的催化裂化汽油比例过大,使炼厂调整汽油生产的技术结构、降低汽油硫含量和改善产品的烃组成成为当务之急。中国车用柴油构成中劣质二次加工柴油比例较高的特点,使适当发展柴油的深度脱硫、脱芳烃技术以提高车用柴油的总体质量水平成为必然要求。随着中国加工进口含硫原油量的逐步增加和环保呼声的不断高涨,燃油清洁化进程必然加快,各种配套的加氢工艺将上升为原油加工的核心工艺,以催化裂化技术为核心的各种联合工艺,以及多产轻烯烃技术和烯烃改质合成技术将进一步发展,各种非加氢工艺的开发也将提到日程。为了有利于资源优化和综合利用,提高炼化整体效益,适当提高炼油单厂、单装置规模,实施渣油深加工和炼化一体化战略仍是今后炼油工业发展的总趋势。

In order to meet the demand of environmental protection,the non-hydrogenation catalyst aimed to reduce the content of olefins in FCC gasoline was studied.The small fixed stock was built to study the influence of catalyst characteristic and reaction condition on the content of olefins in FCC gasoline and the optimum technology conditions were found.The experimental results show that when γ-Al_2O_3 is used as the carrier and transitional metal is used as the active components,under the condition of reaction temperature at 110 ℃,pressure with 0.3 MPa and space velocity with 2.6 h~(-1),the volume fraction of benzene and aromatic hydrocarbon in catalytic gasoline are no more than 2.5% and 40% respectively,and the volume fraction of olefins is decreased from 55% to 30%,which meet the demand of new national standard.At the same time,the octane value of the obtained naphtha is 95 and the disadvantage of decreasing octane value can overcome by hydrogenation process.

为满足环保要求,针对催化裂化汽油烯烃含量较高的问题,研究了一种非加氢降烯烃催化剂。在小型固定床上,考察了催化剂性质和反应条件等对FCC汽油烯烃含量的影响,确定了降烯烃非加氢工艺的最佳工艺条件。研究结果表明,在以氧化铝为担体,过渡金属为活性组分,反应温度为110℃,反应压力为0.3 MPa,体积空速为2.6 h-1条件下,FCC汽油降烯烃反应后,苯的体积分数小于2.5%,芳烃的体积分数有所升高但小于40%,烯烃体积分数由原来的55%下降至30%(荧光法),满足国家汽油新标准要求。同时测定产品油的辛烷值(RON)为95,克服了以往加氢带来的辛烷值降低的缺点。
