Description
Technical field
The invention belongs to technical field of desulfurization, and in particular to a kind of intermediate oil desulfurizer.
Background technique
In the prior art, there are two types of usual ways, respectively hydro-desulfurization method and oxidation desulfurizing method for desulfurization.Hydrogenation
Sulfur method：The technology uses hydrogen sulphur removal from intermediate oil.Because of the process using gas（Hydrogen）, liquid（Midbarrel
Oil）, solid（Catalyst）, so intermediate oil is needed to drip on the surface of catalyst, each hydrogenation reactor need to
It is 30 feet of height less.In addition the process is a balanced reaction, it means that the process needs a series of reactor.Operation
Cost it is very high, because of high hydrogen price, safety and risk-aversion program and equipment.Others are that will lead to diesel oil less
Lubricity.
Oxidation desulfurizing method：The desulfurization technology of oxidation based on the fact that：The more polarity of oxysulfide, be easy it is molten
Agent point（Most application processes are acetonitriles）.The problem of process is:The distillate of some centres is also oxidized.Oxygen sulphur
Compound becomes byproduct, and does not have solution.Intermediate oil is dissolved in acetonitrile, and vice versa.In order to separate
Intermediate oil, oxide, acetonitrile need a fraction system.
Above-mentioned two sulfur method is respectively present different defects：Hydro-desulfurization method uses noble metal as raw material, gas
Body is expensive, and maintenance cost is high, and energy consumption is higher, and uses high risk gas, and operational danger is high.Oxidation desulfurizing method makes
With catalyst, catalyst cannot be reused, and need peroxide catalyzed, at high cost, and need expensive phase transfer catalyst,
Peroxide risk is high.
Summary of the invention
In order to compensate for the shortcomings of the prior art, the present invention provides a kind of intermediate oil desulfurizers.
The present invention is achieved through the following technical solutions：
A kind of intermediate oil desulfurizer, including petroleum tank, desulphurization reaction tank and adsorbent reactivation tank, the petroleum tank pass through
Crude oil pump is connected to desulphurization reaction tank, and desulphurization reaction tank is connected to through solid-liquid separator with adsorbent reactivation tank, on desulphurization reaction tank
It is communicated with adsorbent storage tank.
Further, bottom is equipped with supersonic generator in the adsorbent reactivation tank.
Further, its raw material of adsorbent in the adsorbent storage tank forms in mass ratio：Sieve particle 20-
50 parts；60-95 parts of ethanol solution；9-16 parts of zinc oxide；10-20 parts of manganese dioxide solution.
The beneficial effects of the invention are as follows：A kind of intermediate oil desulfurizer of the present invention may be reused, and have very long
Service life, processing cost is low, not only the treated gasoline product of available super-low sulfur, and loss of octane number is few, hydrogen consumption
Less, liquid yield is high and low energy consumption.
Detailed description of the invention
The present invention will be further described below with reference to the drawings.
Attached drawing 1 is principle schematic diagram of the invention.
In figure, petroleum tank, 2 crude oil pumps, 3 desulphurization reaction tanks, 4 adsorbent storage tanks, 5 solid-liquid separators, 6 adsorbent reactivations
