Embodiment 1

[0022] The properties of the raw material oil of coker wax oil with a distillation range of 230-570°C are as shown in Table 1. Distillation under reduced pressure, and the fraction at 350-520°C is collected.

[0023] The hydrogenation test experiment was carried out on a 100ml fixed bed hydrogenation reaction test device. The constant temperature section in the reactor was loaded with hydrogenation pre-refining, hydrogenation upgrading, hydrogenation post-refining three-stage one-stage hydrogenation catalyst, and the three-stage catalyst was loaded The volume ratio is 2:1:3. The collected distillate is pre-mixed with hydrogen and enters from the upper part of the hydrogenation reactor to react with the catalyst. Hydrogenation was carried out in a single-pass manner in the test. Remove undesired components in raw materials. Control the reaction conditions so that the hydrogen partial pressure is 18MPa, the reaction temperature is 350°C, and the liquid space velocity is 0.9h ...

Abstract

The invention provides a preparation method of environment-friendly rubber tire filling oil, belongs to the technical field of petrochemical engineering, and particularly relates to a method for manufacturing the rubber tire filling oil by using coking gas oil. The preparation method comprises the following steps of: fractionating by taking the coking gas oil as raw oil; then carrying out raw material hydrogenation pre-refining, hydrogenation modification, and hydrogenation post-refining three-stage one-section serial hydrogenation contact reaction under the conditions that a hydrogen partial pressure is 15-18 MPa, the reaction temperature is 350-390 DEG C, the liquid air speed is 0.7-1.0 per hour and the hydrogen / oil volume ratio is 500-700; and finally, fractionating to obtain a three-section product. The preparation method utilizes a secondary-machine poor-quality coking gas oil petroleum fraction as a raw material to expand a new raw material source for the raw materials. The product has good compatibility with rubber; the utilization rate of three raw materials is high; and the conditions are easy to realize.

Description

technical field [0001] The invention relates to a production method of environment-friendly rubber tire filling oil, which belongs to the technical field of petrochemical industry, and specifically relates to a method for producing rubber tire filling oil by using coking wax oil. Background technique [0002] On November 16, 2005, the European Parliament and the Council of the European Union signed the 2005 / 69 / EC regulation on the basis of the 76 / 769 / EEC regulations promulgated on July 27, 1976 in Strasbourg, France. Released on December 9 of the same year. This regulation mainly restricts polycyclic aromatic hydrocarbons (PAHs) in tires and additive oils, and applies to rubber oils and tires (passenger car tires, light and heavy truck tires, agricultural vehicle tires and motorcycle tires). Tires manufactured or retreaded after January 1 are also valid. [0003] 2005 / 69 / EC stipulates that the rubber oil directly put on the market or the operating oil used to manufacture t...
