Embodiment 1

[0057] Prepare 700 solid sodium aluminate to a concentration of 200gAl 2 o 3 / L concentrated sodium aluminate solution, then diluted to a concentration of 35gAl 2 o 3 / L sodium aluminate working solution (a), take SiO 2 28wt% sodium silicate solution, then diluted to a concentration of 150gSiO 2 / L sodium silicate working solution 2L (b). Take a 30L steel plastic tank, open the container valves containing (a) and (b) respectively, and ventilate and feed CO with a concentration of 45v% at the same time 2 Gas, set the flow rate of (a) and (b) so that the reaction time is 1 hour, and quickly adjust the CO 2 flow rate, keep the pH of the system at about 10.0, and the reaction temperature is 30°C. After the reaction of (a) and (b) is completed, stop feeding CO 2 , and then the ventilation was stable for 40 minutes, and the slurry was filtered and washed with 85°C deionized water until neutral. Dry at 120°C for 8 hours, crush and sieve to obtain amorphous silica-alumina GL. ...

Embodiment 2

[0059] Get 100g silicon aluminum GL, 45g modified Y zeolite (SiO 2 / Al 2 o 3 40, unit cell constant 2.432nm, infrared acidity 0.19mmol / g, specific surface 866m 2 / g, pore volume 0.52mL / g) and 310g adhesive made by peptizing nitric acid and SB alumina, kneading, rolling, making extrudable paste, extruding into strips. Carrier A was obtained by drying at 110°C for 6 hours and calcining at 550°C for 4 hours. Then, 80 g of carrier A was impregnated with 200 mL of W-Ni co-impregnation solution in excess for 2 hours, dried at 110° C. for 6 hours, and calcined at 500° C. for 4 hours to obtain the hydrogenation modification catalyst catA. The physical properties of the hydrogenation upgrading catalyst are shown in Table 2.

Abstract

The invention discloses a production method of environment-friendly aromatic hydrocarbon oil for tires. The environment-friendly tire aromatic hydrocarbon oil meeting the European Union standard can be produced by taking positive-sequence furfural extract oil with a relatively high condensation point as a raw material and adopting a hydrotreatment-hydrodewaxing-solvent extraction combined process.The method comprises the following steps: performing hydrotreatment on raw materials under mild conditions to saturate polycyclic aromatic hydrocarbon, performing hydrodewaxing to reduce the condensation point to 0-10 DEG C, and finally performing shallow extraction to obtain the environment-friendly aromatic hydrocarbon oil for tires. The method expands sources of raw materials for producing theenvironment-friendly aromatic hydrocarbon oil, and has the characteristics of strong raw material adaptability and mild process conditions.

Description

technical field [0001] The invention relates to a production method of environment-friendly aromatic oil for tires, in particular to a method for producing environment-friendly aromatic oil by adopting hydrogenation-solvent extraction combined process. Background technique [0002] Rubber filler oil plays an important role as an auxiliary agent in the rubber industry. It can improve the plasticity of the rubber, reduce the viscosity of the rubber and the temperature during mixing, and can promote the dispersion and mixing of other ingredients. Extrusion acts as a lubricant and reduces the hardness of vulcanized rubber and improves its properties. Rubber filler oil can also increase rubber output, reduce costs, improve rubber processing performance and performance, and plays an important role in the rubber processing industry. [0003] As a rubber extender oil with the largest amount and wide application, aromatic hydrocarbon oil (DAE) has good compatibility with rubber and ...
