Abstract
ABSTRACT OF THE DISCLOSURE
A process for the utilization of tar which is separated from the gases derived from gasification of granular fuel under pressure, especially of bituminous coal, and in which the tar separated from the gases in fed back into the pressure gasification cycle of the fuel. The tar is added as a binder in the pelletisation of the fine grained portions of the fuel and is fed into the generator as a constituent of the pellets.
Apparatus for carrying out the process comprises a pressure generator having a feed device for granular fuel, a tar separator, and a pelletising device connected by a tar conveying pipe to the tar separator, for the addition of binder to the granular fuel, the pelletising device conveying the pellets produced thereby into the feed device. The granular fuel is screened to pass only that portion below a predetermined grain size to the pelletiser, the remaining portion being fed directly to the generator.

Description
1C~73;Z09 The invention relates to a process for the utili~a-tion of tar which is separated from the gases derived from the gasification of granular fuel, such as bituminous coal, whereby the tar received is fed back into the gasification cycle of the fuel. The invention also relates to apparatus for carrying out this process.
In a known process separat:ed hydrocarbons, especially tar, are heated and introduced into the reaction or conversion zone of a generator for the gasifi.cation of granular fuel.
Here the hydro-carbons are broken down in the presence of hydro-gen. The process has the advantage that the tar arising during ~, the process of pressure gasification is utilised. Thus the gas is enriched by the low boiling hydrocarbons obtained frorn the tar. For this reason the gas leaves the generator with a higher calorific ~alue. Of course the introduction of the tar into the generator causes considerable difficulties. Amongst other , things the tar, which is generally highly viscous, has to be forced through pipes into the generator with the aid of pumps.
Another problem with the operating of generators fo'r pressure gasification arises rom the dust conte~t of the generated gas. Its dust content is increased with'the increase - of undersize granules ~i.e.^ o~ 0-2 mm grain size~ in the fine -coal which i5 fed to the generator. Up to 70~ of the coal -obtained by the usual extractlon and preparatlon methods is li~aly to be u~dersize. For this reason the fine coal must bP
graded~before it is fed to the generator so that the coal,fed -to the~generator has generally a grain size of 2-30 mm. Use of coal having a lower grain~slze than this leads to an un- ' desirable high dust content in the'gas generated~ Furthermore, ~ it leads to a poor draught in the,standing pillar of fuel in ~ -~the body of the generator.

~C~73Z(~9 According to one aspect of the invention, there is provided a method of producing gas from a granular fuel com-prising feedin~ said fuel to a gasifier, separating tar from the gas produced by the gasifier, and using said tar to pelletise fuel being fed to the gasifier.
According to a further aspect of the present invention there is provided an apparatus for producing gas from ~ranular fuel which comprises a gasifier, a tar separator connected to the output of the gasifier and a fuel pelletiser connected to utilise tar fror.t the separator, the output o~ the pelletiser being connected to the gasifier.
According to a ~rther aspect o~ the present invention, ~ , there is provided a process for the utilisation of tar in the ; gasification under pressure of granular bLtuminous coal which comprises the steps of, pelletising under ambient temperature conditions a fine graded dust-like portion of bituminous coal with tar serving as a binder, feeding pellets in grain condi-tion directly to a pressure generator for pxoducin~ gas by reaction with the coal, separating tar obtained ~rom such ~0 pellets and issuing from the reaction zone of the generator and employing same in the pelletisiny step and utilising the - pellets in green condition as the transportin~ vehicle for tar constituents through the pressure generator.
Accordingly, the equipment hitherto requixed for the .
introduction of the tar into the reaction zone of ~he generator is made superfluous. The tar arrives in the reaction zone of .

According to a further aspect of the present invention there is provided an apparatus for producing gas from ~ranular fuel which comprises a gasifier, a tar separator connected to the output of the gasifier and a fuel pelletiser connected to utilise tar fror.t the separator, the output o~ the pelletiser being connected to the gasifier.
According to a ~rther aspect o~ the present invention, ~ , there is provided a process for the utilisation of tar in the ; gasification under pressure of granular bLtuminous coal which comprises the steps of, pelletising under ambient temperature conditions a fine graded dust-like portion of bituminous coal with tar serving as a binder, feeding pellets in grain condi-tion directly to a pressure generator for pxoducin~ gas by reaction with the coal, separating tar obtained ~rom such ~0 pellets and issuing from the reaction zone of the generator and employing same in the pelletisiny step and utilising the - pellets in green condition as the transportin~ vehicle for tar constituents through the pressure generator.

The pelletisation process preferably uses the undersize grains of 0-2 mm grain size. The pellets themselves have,

however, the required size for pressure gasification, pref-erably about 20 ~n. Thus they cor~espondingly reduce the dust carried out in the generator gas. The reduc-tion of the dust content ma]ces it possible for the gas scrubbing plant which follows the generator in process sequence, to be smaller ~han hitherto. Also the mixture obtailled from the scrubber, which consists of tar and dust, exhibits a more favourable tar - dustratio than hitherto. Eecause of this the conveying properties of the tar used for pelletising are improved.
The incidence of dust when loading the fuel into the generator is also reduced. I
For practical purposes the fuel is graded before . pelletising, e.g. in order to exclude the coarse proportion which can be used for gasifying without the necessity of pelletisation.
The following is a description of an embodiment of the invention with reference to the accompanying drawing.
The single figure is a schematic lay-out of a pressure gasification process with a return tar feed.
A pressure generator 1 r~ceives granular fuel, namely ~-coal, at 2 an~, as gasification medium, steam at 3. The generator produces gas by reaction with the fuel, whlch gas leaves the generator 1 at 4. The ash resulting is rernoved at 5.
The fuel required for tlle operating of the generator 1 consists of fine coal with a granular ~radin~ of 0-30 n~ grain size. This is delivered onto a tensionable screen 7 by means ~`~ of a conveyor 6, which screen separates the granular sizes 0-3 mm grain si~e from the coarse proportion of 3-30 mm grain size. The fuel remaining o~ the screen (3 30 mm grain si~e) is fed dlrectly into the generator by a conveyor 8. That pass-ing through the screen (0-3 m~l grain size) arriv~s on a ~ ~ -3- ~ ~

In fact, the tar-, , , dust amount with respect to the pellets is reduced consider-ably. Furthermore, no transport of the tar-dust mixture is necessary.
