1. the method for a waste lubricating oil continuous production oil fuel is characterized in that stock oil is carried out standing sedimentation to be taken off and live together reason, takes off the condition of living together reason to be:

  • 20 ℃



    90 ℃

    of temperature, 6~

    24 hours time;

    After isolating moisture and mechanical impurity, under stirring condition, add sorbent material, catalytic cracking catalyst and molecular weight regulator;

    With stock oil weight is benchmark, and wherein the granularity of sorbent material is less than 20 orders, and add-on is 0~

    15 weight %, and the catalytic cracking catalyst add-on is 0~

    0.6 weight %, and molecular weight regulator is C 12

    C 22Hydrocarbon component, add-on is 0~

    20 weight %, again stock oil is delivered in the tubular oven with overheated steam after heat exchange, heater outlet temperature can be controlled between 260~

    520 ℃

    , the add-on of superheated vapour should be controlled at material quantity weight 2~

    15% between, the stock oil residence time is 1~

    10 minute in tubular oven, and the oil gas of furnace outlet separates through separation column, obtains different oil fuel.
