A process for the production of synthesis gas from coke is suggested, in which (a) hard coal is subjected to dry pyrolysis, resulting in the production of a gas mixture containing hydrogen, methane, nitrogen and carbon monoxide as major constituents and carbon sulphides as minor constituents, (b) the gas mixture is subjected to hydrogenation at a temperature in the range of 200 DEG C to 280 DEG C over a sulphidic cobalt molybdenum catalyst provided on an aluminium oxide carrier material, and (c) the hydrogen sulphide obtained from hydrogenation is separated from the gas mixture.
Description
Technical field
The invention belongs to coke manufacturing technology domain variability and relate to from coke-oven gas, remove carbon sulfide novel process and new catalyzer and application thereof.
Background technology
Coke-oven gas (synonym: coke gas) is dry distillation acquisition from hard coal (hard coal) in coke furnace factory.As main component, this gas is usually containing the carbon monoxide of the hydrogen of the 55wt% that has an appointment (weight percent), the methane of 25wt%, the nitrogen of 10wt% and 5wt%.For this reason, coke-oven gas is normally qualified as the synthetic gas of chemical reaction, but disadvantage is the content of carbonyl sulfide (carbonyl sulphide) and carbon sulfide (carbon disulphide), it must be removed in advance, this is because they such as serve as catalyzer poison in reaction subsequently.Thus, catalyzer is constantly cleaned and is even replaced, and this is directly related to workload and cost and week then do not wish to occur due to factory.
A kind of method removing undesired carbon sulfide from coke-oven gas coal gas is stood catalytic hydrogenation and transforms sulphur compound to be hydrogen sulfide.Although this gas also undesired, it can be easy to be washed by means of moisture alkali lye such as ammonia solution.
According to prior art, relevant technique is known.Such as, German patent application DE 1545470 A1 (Pichler) suggestion hydrogenation carbon sulfide on cobalt molybdenum, nickel molybdenum or nickel cobalt-molybdenum catalyst is hydrogen sulfide, and then it can be separated.Temperature of reaction in this embodiment is higher than 550 DEG C.
For coke-oven gas hydrogenating desulfurization (hydrodesulphurisation), the use of catalyzer based on nickel, cobalt, molybdenum or palladium also can find in various Japanese patent application comparatively early, such as JP 59 145288 A2 (Shinnittetsu) or JP 59 230092 A1 (Hitachi).And these processing methodes accordingly.
Similar technique also can be known from German patent application DE 2647690 A1 (Parsons), which proposes the carbon compound of hydrogenation sulfur-bearing on the catalyzer on cobalt, molybdenum, iron, chromium, vanadium, thorium, nickel, tungsten and/or uranium basis and removes the hydrogen sulfide obtained in extraction column by means of alkali hydroxide soln.The sulfide of above-mentioned metal is proposed as concrete catalyzer.But involved shortcoming, in the case, catalyzer needs the temperature of minimum 260 DEG C and hydrogenation must preferably carry out, partly even higher than 400 DEG C showing at higher temperature.Be in the reason of energy cost, this is undesirable especially; In addition, by changing the component of gas, namely can there is methanation in this temperature.
Although prior art processes is changed carbon sulfide into hydrogen sulfide in the mode of high production capacity and is therefore changed the synthetic gas of coke-oven gas into enough high-quality, they all relate to substantial shortcoming, namely these techniques must be carried out at the very high temperature being equivalent to more than 280 DEG C, otherwise sufficiently high turnover ratio is difficult to realize.
Therefore, the object of the invention is to improve existing technique, if any, as long as carbon sulfide and organosulfur compound (such as thiophene) are converted hydrogen sulfide substantially quantitatively, and is showing at the temperature reduced.Further, the mass ratio that this technique is intended to guarantee to maintain oxycarbide and methane is constant, namely prevents methanation.
Summary of the invention
Theme of the present invention is for the method by coke production synthetic gas, wherein
A () hard coal stands stem cracking, cause containing hydrogen, methane, nitrogen and carbon monoxide as the generation as the gaseous mixture of a small amount of component of main ingredient and carbon sulfide,
At the temperature of (b) gaseous mixture within the scope of 200 to 280 DEG C, the sulfide cobalt-molybdenum catalyst that provides on alumina supporting material carries out hydrogenation, and
C hydrogen sulfide that () obtains from hydrogenation is separated from described gaseous mixture.
Astoundingly, the known sulfide cobalt-molybdenum catalyst for carbon sulfide hydrogenation even lower than 280 DEG C and preferably lower than 260 DEG C at there is high reactivity and optionally feature, if they are deposited on alumina supporting material.Carbon sulfide in fact at least 95 (volume) % is hydrogenated and is reacted into hydrogen sulfide and does not observe hydrogenation to the impact of oxycarbide on the ratio of methane.This is a beyond thought result, because the instruction of document DE 2647690 A1 according to introductory song citation, people's expection also can promote with the catalyzer of sulphided form mainly containing cobalt and molybdenum the degree that undesired methanation be can not ignore to, if particularly reaction is carried out as usual under stress.
Coke coal gas is produced by hard coal cracking
In the process of hard coal dry distillation or cracking, under it occurs in 900 to 1400 DEG C of temperature, the volatiles of coal is released and forms porous coke, and it is now substantially only containing carbon.By condensate fractionation, unstripped gas is broken down into tar, sulfuric acid, ammonia, naphthalene (naphthalene), benzene and so-called coke coal gas.The latter is made up of hydrogen, methane, nitrogen and oxycarbide and can be further used in chemical reaction after fully processing to obtain synthetic gas.
Hydrogenation technique
The hydrogenation of cracked gas can carry out in a conventional manner, and to this, mainly fixed-bed reactor have proved optimal, because catalyzer is provided as bulk layers or fixing filler (packing) with bulk form.Because bulk material is more easy to form passage and is therefore formed with Non-Uniform Flow distribution, in this embodiment, preferably catalyzer is arranged in reactor in the mode of filler.
But the advantage of the hydrogenation in fixed-bed reactor is that the output of high space/time is achieved, Here it is why according to technique of the present invention also can about 500 to about 1500 ls/h (l/h) and preferably approximately 1000 carry out to high GHSV (gas hourly space velocity, gas (little) space-time () speed) value of about 1200 ls/h (l/h).Another advantage is for product withdraw without the need to special measure, because reactant-i.e. cracking coal gas and hydrogen-be preferably collectively incorporated in the bottom of reactor, through causing the catalyst bed of hydrogenation and leaving reactor as product at top.
As already mentioned in beginning, a specific advantages of this processing method is sulphur compound hydrogenation on the catalyzer that will use according to the present invention, makes to react to carry out under the condition of obvious milder and transforming completely of carbon sulfide and any sign without methanation becomes possibility.Range of reaction temperature between 200 to 280 DEG C, and preferably has sufficient speed of response between 240 to 260 DEG C.Reactor can from indirect heating, and this causes higher energy expenditure; Or reactive component can be heated before they are incorporated into reactor, it can mix by means of in the nozzle such as adopting the work of Venturi (Venturi) principle.
Further, reaction can namely at barometric point or add pressure and carry out in the scope of 1 to 15 bar.Present embodiment preferably adopts about 5 to the pressure in the scope of about 10 bar, because this is conducive to output and speed of response.
