The remainder of sugarcane and other crops after seed is harvested, rich in organic matter etc. in stalk.At present, typically stalk is carried out
The processing such as burning, existing straw burning causes air pollution to air, while wastes the energy.
It is among prior art to use water HTHP degree straw as the development of technology starts to enter stalk industrial treatment more
Stalk is handled, and its cost is high, and danger coefficient is high, cumbersome using multiple reactor steps, or uses this inert gas of nitrogen
Cracked as carrier.There is cost height in existing straw splitting technique, practical operation difficulty is big, and process route length investment is big etc.
Shortcoming.Therefore, prior art needs further improvement and developed.
The content of the invention
In view of above-mentioned the deficiencies in the prior art, it is an object of the invention to provide a kind of liquefied method of straw splitting, with
Processing cost is reduced, thoroughly to handle stalk.
In order to solve the above technical problems, the present invention program includes：
A kind of liquefied method of straw splitting, it comprises the following steps：
A, stalk is crushed, makes stalk crushed material with conduction oil by 1:4-6 ratio is sufficiently mixed to obtain mixture, by mixture
The first cracking reactor is imported, under conditions of 300 DEG C -360 DEG C, 10-15Pa, cracking ten minutes for the first time is carried out, obtains thick
Product；
B, above-mentioned crude product is imported into the second stage reactor and carries out sudden strain of a muscle cracking, and hydrogen and catalysis are added into the second stage reactor
Agent, under conditions of 300 DEG C -360 DEG C, 10-15Pa, carry out dodging to crack for the second time completing in 0.5 second；
C, caused gaseous material in step B is cooled down to obtain just tar, remaining gaseous material be fractionated, after fractionation
Product carry out water-oil separating, obtain hydrate and semi-finished product oil, hydrate be subjected to pyrolkigneous liquid recovery, the calorific value of semi-finished product oil
It is identical with 75%-80% diesel oil calorific value.
The liquefied method of described straw splitting, wherein, above-mentioned steps B specifically also includes：After cracking being dodged second
Residue import horizontal screw machine handled, conduction oil therein is reclaimed, by the stalk Slag recovering after cracking.
The liquefied method of described straw splitting, wherein, above-mentioned steps A also includes：By it is broken at the beginning of stalk be 2 centimetres -3 centimetres
Stalk block, and stalk block is dried ten minutes to 15 minutes under the conditions of 100 DEG C, and cleaned, by the straw after removal of impurities
Stalk block crushes and crosses 40 mesh sieves, obtains above-mentioned stalk crushed material.
The invention provides a kind of liquefied method of straw splitting, and water or inert gas are replaced with conduction oil, has life
It is low to produce cost, is easy to process parameter control, is easy to fully contact with material, it is less demanding to pressure and temperature, it is easy to accomplish work
Industry, can reach disposable cracking, and synchronous hydrogenation can take off oxygen atom in process so that the energy density of product increases
Greatly, abundant biomass energy can rationally be utilized, thus it is possible to vary whole fuel industry structure, be greatly entering for prior art
Step.
Brief description of the drawings
Fig. 1 is the schematic flow sheet of the liquefied method of straw splitting in the present invention.
Embodiment
The invention provides a kind of liquefied method of straw splitting, to make the purpose of the present invention, technical scheme and effect more
Add clear, clear and definite, the present invention is described in more detail below.It should be appreciated that specific embodiment described herein is only used
To explain the present invention, it is not intended to limit the present invention.
The invention provides a kind of liquefied method of straw splitting, as shown in Figure 1, it comprises the following steps：
Step 1, stalk is crushed, make stalk crushed material, catalyst and conduction oil by 1:4-6 ratio, which is sufficiently mixed, is mixed
Compound, mixture is imported into the first cracking reactor, under conditions of 300 DEG C -360 DEG C, 10-15Pa, carry out first time cracking
Ten minutes, obtain crude product；
Step 2, above-mentioned crude product is imported into the second stage reactor and carries out sudden strain of a muscle cracking, and add into the second stage reactor hydrogen and
Catalyst, under conditions of 300 DEG C -360 DEG C, 10-15Pa, carry out dodging to crack for the second time completing in 0.5 second；
Step 3, caused gaseous material in step 3 is cooled down to obtain just tar, remaining gaseous material is fractionated, it is right
Product after fractionation carries out water-oil separating, obtains hydrate and 55% semi-finished product oil, and hydrate is carried out into pyrolkigneous liquid recovery, partly into
The calorific value of product oil is identical with 75%-80% diesel oil calorific value.Straw splitting is oily into bio-oil and industrial chemicals, final semi-finished product
Calorific value is equivalent to the 75%-80% of diesel oil, the alternative petroleum of this semi-finished product oil, and oil quality is better than oil, further adds
