preparation example Construction

[0030] The preparation process of the hydrogenation modification catalyst of the present invention comprises: after uniformly mixing the amorphous silica-alumina and the modified Y zeolite, adding a binder, kneading, rolling into agglomerates, extruding on an extruder to obtain a carrier, Reload the hydrogenation active metal.

[0031] The preparation method of amorphous silicon aluminum used comprises the steps:

[0032] a. Prepare sodium aluminate solution and sodium silicate solution;

[0033] b. Add the sodium aluminate solution and the sodium silicate solution into the gel forming tank concurrently, and ventilate and feed CO at the same time 2 gas, adjust sodium aluminate solution, sodium silicate solution and CO 2 Flow rate, control the pH value of the material in the gel tank to 9-11, control the neutralization reaction temperature to 20-50°C, and the neutralization reaction time to 0.5-1.5 hours;

[0034] c. Under the controlled temperature and pH value of step b, t...

Embodiment 1

[0049] 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

[0051] Get 80g silicon aluminum GL, 30g 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 250g 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 A was impregnated with 200 ml of a Mo-Mi 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 hydrogenation upgrading catalyst A. The physical properties of the hydrogenation upgrading catalyst are shown in Table 1.

Abstract

The invention discloses a method for treating rosin, which comprises the following content: the rosin mixed oil enters a liquid-phase hydrogenation treatment reaction zone after being mixed with hydrogen in a hydrogen mixing tank, and is sequentially contacted with a hydrogenation refining catalyst and a hydrogenation upgrading catalyst A to carry out hydrogenation Reaction; the hydrotreating effluent enters the hydroreforming reaction zone after being flashed by the flash tank, and the hydroreforming reaction zone uses the hydrogenation reforming catalyst B containing amorphous silica-alumina and modified Y zeolite, in the presence of hydrogen Next, carry out the hydrogenation upgrading reaction; the obtained hydrogenation upgrading product is separated to obtain the transformer oil. The method of the invention uses rosin as a raw material to produce transformer oil, can broaden the raw material source of transformer oil products, and produce special oil products meeting higher quality requirements.

Description

technical field [0001] The invention relates to a method for treating rosin, in particular to a process for producing special oil by hydrogenating rosin as a raw material. Background technique [0002] Rosin is a natural resin that is extremely abundant in nature, does not contain impurities such as sulfur and nitrogen, and comes from renewable pine forest resources. my country is a big country of rosin production, with an annual output of more than 600,000 tons of gum rosin, ranking first in the world, and with the increase of recoverable gum pine forest area in my country, the output of rosin will continue to increase. In 2010, the annual output of rosin exceeded 800,000 tons, while the utilization rate of deep processing of rosin in my country was only 35%, mainly exporting gum rosin, which caused a huge waste of rosin resources in my country. added value. The main component of rosin is abietic acid type resin acid (molecular formula is C 19 h 29 COOH), mostly a monoca...
