MerayL ALcoHOL—METHANOL.
Two processes, the Patart and the Badische Anilin und Soda
Fabrik, are operating in Europe for the synthesis of methyl alcohol
which is known commercially as methanol.
The synthesis is effected by passing mixtures of producer gas
(carbon monoxide) and hydrogen at a pressure of 200 atmospheres and
a temperature of 400—500 deg.C. over a catalyst of zine oxide and
chromic acid. On cooling the reaction product under pressure, a good
yield of practically pure methyl alcohol is obtained. The process is
stated to be economical and during last year methyl alcohol has been
exported from Germany at a price which threatens the wood
distillation industry.
SYNTHOL.
Carbon monoxide is also hydrogenated in the presence of iron and
potash at a temperature of 410deg.C. and a pressure of 100
atmospheres to a complicated mixture of organic derivatives which
1s sold as a motor fuel under the name of ‘* Synthol.”’
It is significant that the German Dye Trust is erecting large plant
for the carbonisation of coal in the centre of the German coal area
with the object of producing either motalin or methanol to the extent
of 250,000 to 300,000 tons per annum.
Germany's annual consumption of motor fuel is 600,000 tons, and
it is the intention to increase production to this amount.
The Trust has made provision for the marketing of the fuel by
acquiring a half interest in the Deutsche Gasolin Company and it
appears that the oil companies fear the competition of the new fuel
in the German fuel market, for both the Standard Oil Company and
the Shell Company have entered into partnership with the Trust. each
having acquired 259, of the Deutsche Gasolin shares.
In conclusion it might be mentioned that the Maihle process, in
which vegetable oils are cracked, and the products hydrogenated in
the presence of a catalyst, is in operation in Belgium on an experi-
mental scale. If the process develops the oil-bearing seeds of the
tropics will play a part in supplying future requirements of fuel oil.
Summary.
In view of the increasing demand for liquid fuel and the doubtful
adequacy of future supplies of petroleum, the possibilities of producing
alcohol as an alternative fuel are discussed.
The suitability of the different raw materials is considered and
allowing for a considerable fall in the price of petrol it is concluded
that alcohol can be produced commercially in Kenya from molasses
and possibly from cassava.
Even though it can compete with petrol attention is drawn to the
possibility that agricultural alcohol for power purposes may be driven
from the market by synthetic alcohol or by a competitive fuel produced
by the liquefaction of coal.
Mr. SIMPSON regretted that, as agriculturists, they could have
very little to say. The question of industrial alcohol was a most
important one to tropical and sub-tropical countries and had been
considered very carefully for some considerable time. In Uganda,
the question was one of very grave importance. as motor transport
