Technical Features:
1.
Diesel ultra-deep hydrodesulfurization technology is used to process various diesel fraction raw materials, including direct-distilled diesel, catalytic diesel and coking diesel, etc.
, and the target product is clean diesel components with very low sulfur content
.
2, the use of patented catalyst, the catalyst hydrodesulfurization and denitrification activity is very high, good selectivity, can be operated at a higher airspeed, lower temperature, low gas yield, high
diesel yield.
3.
When the sulfur content of raw material diesel is 1.
0wt%-2.
0wt%, the sulfur content of product diesel is less than 50μg/g or less than 10μg/g, and the cetane number is 3-8 higher than that of raw material
.
4.
The investment and operation cost of the plant are low, and the public works consumption and raw material consumption of the product are comparable
to the conventional diesel hydrogenation treatment device.
Production process: The process flow of this technology includes two parts
: reaction and fractionation.
After the raw material oil is heat exchanged, heated, it enters the fixed bed reactor, and hydrodesulfurization, nitrogen desulfurization and olefin saturation reaction occurs, and the reaction product is separated from the gas product, and the liquid product is fractionated to obtain clean diesel components
.
