Description
Technical field
A kind of high-sulfur light distillate and organic heat carrier feedstock oil hybrid process technique, belong to oil hydrogenation technical field.
Background technique
Oil hydrogenation technique refers in certain temperature and hydrogen pressure, by the catalytic action of catalyst, makes feedstock oil and hydrogen
Gas react and then improves oil quality or obtain the technique of target product.Different raw materials is directed in oil hydrogenation technique
Property selects different catalyst to carry out hydrogenation reaction, obtains different target products.
Two kinds of raw material oil natures of high-sulfur light distillate and organic heat carrier are compared:
High-sulfur light distillate raw material oil nature: density (20 DEG C) 803.3kg/m3, boiling range, IBP154 DEG C/10%205 DEG C/30%228
DEG C/50%240 DEG C/70%250 DEG C/90%265 DEG C/95%276 DEG C/EBP298 DEG C, -32 DEG C of condensation point, 53 DEG C of flash-point (opening), viscosity
(40 DEG C) 1.878mm 2.s-1, 5.1 μ g.g of nitrogen content-1, 5147 μ g.g of sulfur content-1；
Organic heat carrier raw material oil nature: density (20 DEG C) 835.3kg/m3, IBP188 DEG C of boiling range/10%311 DEG C/30%368 DEG C/
50%392 DEG C/70%412 DEG C/90%449 DEG C/95%465 DEG C/EBP491 DEG C, -34 DEG C of condensation point, 148 DEG C of flash-point (opening), viscosity
(40 DEG C) 11.78mm2.s-1, 8.2 μ g.g of nitrogen content-1, 9 μ g.g of sulfur content-1。
It compares high-sulfur light distillate known to high-sulfur light distillate feedstock oil and organic heat carrier feedstock property and organic heat carries
Two kinds of feedstock oils of body, boiling range, S content, viscosity differences are big.
At this stage oil hydrogenation work there are the shortcomings that it is as follows:
1, a set of oil hydrogenation device can only be suitble to a kind of oil hydrogenation to react, and product structure is single.
2, to guarantee that sulfide type catalyst does not lose S non-inactivation, sulfide type catalyst is merely able to be suitble to processing high-sulfur oil product, no
It is capable of processing low-sulfur or sweet pennsylvania crude product.It is filled into if the sulfide type catalyst long period cannot obtain sulphur in raw material, will cause sulphided state
Metallic catalyst loses catalytic action at elemental metals by hydrogen reducing, causes permanent deactivation；
WS3+3H2→W+3H2S, NiS+ H2→Ni+H2S, MoS3+3H2→Mo+3H2S。
3, current organic heat carrier processing technology is no sulfur catalyst, and subsequent technique is micro- without desulfurization process, therefore in oil product
Amount inorganic sulfur is difficult to remove.
4, using clay-filtered decoloration, complex process generates solid waste.
