【摘要】：当前环保形势日益严峻,巨大的环保压力促使政府要求油品质量升级加速,我国大部分地区汽油实行的是国V标准,即烯烃含量≤24%(质量分数),硫含量≤10ppm。在我国现有的成品汽油中,催化裂化汽油约占70wt%,常规催化裂化汽油烯烃含量约占40～50wt%,难以满足国V汽油标准,各炼油化工企业除了努力增加汽油调和组分外,解决方案在于降低催化汽油的烯烃含量,同时考虑到经济效益,汽油辛烷值需要保持较高水平。本文研究的内容如下:多产异构烷烃工艺旨在降低汽油烯烃含量的同时多产异构烷烃,其研究法辛烷值基本不变,马达法辛烷值有所提高,保持辛烷值基本不变。本文通过多产异构烷烃工艺在呼和浩特石化公司催化裂化装置运行的实际情况,从产品分布、物料收率、装置能耗以及不同催化剂应用等几个方面提取生产数据,通过生产数据分析研究多产异构烷烃工艺的优势所在。对装置运行中出现的问题进行深入分析研究,提出解决方案。研究结果显示,较常规的催化裂化,该工艺对于提高催化裂化装置汽油产品质量和改善催化裂化装置产物分布有着良好的效果,汽油辛烷值达到90以上,产品总液收达到85%以上。使用不同催化剂生产工况下,重油裂解催化剂总体效果优于专用催化剂,利于工厂效益的提升。对于生产中出现的工艺和设备问题,通过相应解决方案,得到了解决或者改善,有助于装置长周期高效运行。
[Abstract]:The current environmental situation is increasingly serious, prompting the government to huge environmental pressure to upgrade the quality of oil to accelerate, gasoline in most areas of our country is in the V standard, the olefin content less than 24% (mass fraction), the sulfur content is less than 10ppm. in our existing gasoline, FCC gasoline accounts for about 70wt%, the conventional FCC gasoline the olefin content of about 40 ~ 50wt%, it is difficult to meet the V standard gas, the oil refining and chemical enterprises in addition to increase the gasoline blending components, the solution is to reduce olefin content in FCC gasoline, taking into account the economic benefits, the octane number of gasoline needs to maintain a high level. The contents of this paper are as follows: the maximum isoparaffin process to reduce olefin content and maximizingiso paraffins, the research octane number unchanged, octane number increased, keep the octane number remained unchanged. In this paper, by the prolific In the actual operation process of isoparaffin Hohhot Petrochemical Co catalytic cracking unit, from the product distribution, material yield, energy consumption and several different catalyst applications from production data, production data through analysis of advantages of maximizingiso paraffins process. The thorough analysis and Research on the emergence of device operation problems, propose solutions. The results show that compared with the conventional catalytic cracking, the process has a good effect for improving FCC gasoline product quality and improve the FCC product distribution, gasoline octane number reached more than 90, the total liquid products reached more than 85%. The use of different catalysts under production conditions, the overall effect is better than that of heavy oil cracking catalyst for special catalyst the factory to improve efficiency. For the problem of process and equipment during production, through the corresponding solutions, The solution or improvement is helpful to the long cycle and efficient operation of the device.
