.STABLE SUSPENSION 'AIl'D IASTE OF COAL.
Ho Drawing. Application filed March 23, 1927, Serial No. 177,832, and in Germany March 24, 1926.
A variety of of coal in which agents.
many purposes, ma the aforementione dispersion of coal, by alcohols, such as methanol and may be obtained by stabilising said alcohols, for example, alkali metals or ammonia, pyridine, aniline and the like.
By suitably coal may already contain example crude coal-tar oils.
chemical purposes such hydrogenation of coal.
The following examples will further illustrate the nature of the said invention but the invention is not limited to these examples.
The parts are by weight.
Example I.
10 parts of fine] nite) are treated rocesses are already known for the production of suspensions or pastes processes viscous hydrocarbons or oils are employed as dispersing proportioning the amount of coal, it is possible to obtain stable, oleaginous suspensions or pastes of coal possessing from low to maximum viscosity. In many cases the stability of the suspension or paste of be further improved by an addition of mineral oils, more especially those which finely divided carbon, as for etroleum or certain brownhe resulting suspensions or pastes are highly suitable for example as heating oils or as original materials for as the destructive ground brown-coal (ligor several hours in a ball mill or disintegrator with 25 parts of crude isobutyl alcohol (products of high boiling point of the synthesis of methanol from oxide of carbon) containing 1 part of sodium hydroxid in solution until the mixture no longer separates into its components and a stable, oleaginous and viscous suspension of brown coal has been formed.
Ewample 2.
1 part of finely ground brown-coal is treated with 5 parts of crude isobutyl alcohol ner described in Example 1, a stable suspension of brown coal, possessing lower viscosity than that described in the foregoing example, being produced.
Ewample 3.
40 parts of brown. coal are treated with 90 parts of crude isobutyl alcohol, 1 part of sodium hydroxid and 5 parts of brown-coal tar oil, as in Example 1, a highly viscous mass, specially adapted to form the original material for the destructive hydrogenation of coal, being obtained. y
Other varieties of coal or bitumens, for. example pit coaland thelike, can also betreated in the same manner as hereinbefore described. 5
Whatwe claim is:
1. The process of producing stable suspensions of coal which consists in mechanically dispersing the coal in a liquid alcohol with an addition ofa base soluble therein.
2. The process ofproducing stable suspensions of coal which consists in mechanically dispersing the coal in crude synthetic isobutyl alcohol.
In testimony whereof we have hereunto set our hands.
