Embodiment 1

[0027] Paraffin fraction raw material 1 passes through the heating furnace to reach the required temperature and fully mixes and dissolves hydrogen in the SK static mixer, and then enters the hydrogenation reactor. The reaction conditions are: hydrogen partial pressure 6.8MPa, volume space velocity 1.0h -1 , The reaction temperature is 242°C, and the volume ratio of hydrogen to oil is 100:1. The raw material wax properties and product properties are listed in Table 2.

[0028] As can be seen from Table 2, high-quality paraffin wax products can be produced using this process technology.

Embodiment 2

[0030] The paraffin fraction raw material 2 is fully mixed with hydrogen and enters the hydrogenation reactor after passing through the heating furnace. The gas-liquid mixer adopts a SH type static mixer. The reaction conditions are: hydrogen pressure 5.2MPa, volume space velocity 0.9h -1 , The reaction temperature is 231° C., and the volume ratio of hydrogen to oil is 110:1. The raw material oil properties and product properties are listed in Table 3.

[0031] As can be seen from Table 3, high-quality paraffin wax products can be produced using this process technology.

Embodiment 3

[0033] The paraffin fraction raw material 3 is fully mixed with hydrogen and enters the hydrogenation reactor after passing through the heating furnace. The reaction conditions are: hydrogen partial pressure 6.8MPa, volume space velocity 1.0h -1 , The reaction temperature is 238°C, and the volume ratio of hydrogen to oil is 120:1. Half of the hydrogen is mixed with the raw materials through the SL gas-liquid mixer, and the other half is directly fed into the reactor through the pipeline. The raw material oil properties and product properties are listed in Table 4.

[0034] As can be seen from Table 4, high-quality paraffin wax products can be produced using this process technology.

Abstract

The invention relates to a hydrogenated modification method for a petroleum wax substance, which comprises the following steps of: fully mixing the petroleum wax substance serving as a raw material and hydrogen in a gas-liquid mixer through a heating furnace, then making the mixture contact a hydrogenation catalyst in a low hydrogen-wax volume ratio under mild process condition, and performing the conventional hydrogenation reaction. Compared with the conventional hydrogenation process, the method can achieve the same effect as the conventional refining under the mild process condition. The method can produce high-quality paraffin products of various brands, and has the advantages of simple process flow, stable operation, good product property and capabilities of reducing the energy consumption of a device, improving the product yield and newly building a hydrogenation device or reforming an old device.

Description

technical field [0001] The invention relates to a method for hydrogenation and upgrading of petroleum wax substances. Background technique [0002] Petroleum wax is an important petroleum product, mainly including paraffin wax, microcrystalline wax, vaseline, etc. Its output is not large, but because of its special physical and chemical properties, it is one of the indispensable raw materials for many sectors of the national economy and is widely used in Electronics, metallurgy, light industry, chemical industry, papermaking, medicine and daily necessities chemistry and other industries. The price of petroleum wax products is relatively high. It is a product with less input, more output and high added value. It is also one of the main export products of my country's petrochemical enterprises. [0003] The production of petroleum waxes mainly includes sulfonation, hydrogenation and adsorption. Among them, the hydrogenation method has been widely used because of its strong a...
