      Recently, Jilin Petrochemical Co.
    , Ltd.
    has solved the problem of gasoline quality upgrade through scientific optimization and solved the problem of gasoline quality upgrade.
    National VIB standard vehicle gasoline was put on the market 7 months ahead of schedule

    .
    Up to now, Jilin Petrochemical has produced 211,300 tons of National VIB standard gasoline

    .

      It is reported that on January 1, 2023, the whole country will fully supply National VIB standard vehicle gasoline.
    Its use will reduce carbon deposits and colloidal deposition in automobile engines, bring a stronger sense of power, and reduce consumer vehicle maintenance costs.
    Engine life

    .
    From the perspective of technical indicators, compared with the national VIA standard gasoline, the olefin index has dropped from 18% to 15%, and the carbon monoxide and nitrogen oxide emission indicators have also dropped significantly.
    The production difficulty is more difficult, the technical requirements are higher, and the quality requirements are stricter.

    .

      In order to complete the task of upgrading oil product quality with high standards and high quality, Jilin Petrochemical established a joint research team, adhered to daily analysis, weekly meetings, and monthly summaries, carefully studied and verified the research path, and scientifically formulated the overall implementation plan, blending plan and "8+2" "Special work plan
    .
    "At the stage of implementing the National VIA standard of gasoline, the olefin content of gasoline has reached the bottom.
    If we want to upgrade the quality of gasoline to National VIB without adding new projects and using mixed benzene, the difficulty is mainly focused on the reduction of olefins in the catalytic cracking unit.

    ” said Zhou Bo, deputy director of Jilin Petrochemical Refinery
    .

      In order to reduce the olefin content to the ideal range, the technicians of Jilin Petrochemical started by adjusting the catalyst formula, conducted research and exchanges with scientific research institutes and catalyst manufacturers to clarify the direction of catalyst formula adjustment, and reasonably allocated the normal slag and slag reduction in the catalytic cracking unit.
    A series of optimization measures such as adjusting the reaction temperature were implemented, and finally the olefin index of the catalytic cracking unit was reduced by more than 2.
    5%, and the octane number of the alkylate was 0.
    5 units higher than before the breakthrough

    .

      In addition, Jilin Petrochemical also formulated a national VIB gasoline blending plan with the main line of "three sets of catalytic cracking units to reduce olefins", focusing on the goal of stabilizing the market supply after the oil product upgrade, and carried out 5 laboratory blending demonstrations and 2 amplifications successively.
    experiment

    .
    The results show that the national VIB standard motor gasoline that has undergone olefin reduction and optimized blending can fully meet the needs of the Jilin region under different working conditions in winter and summer
