For the removal of SO.sub.x and NO.sub.x from effluent gas, the gas, before being passed through a Selective Catalytic Reduction catalyst bed for reduction of at least a part of the nitrogen oxides in the gas, is subjected to at least substantially complete desulfurization in a coke bed. The desulfurized and denoxed gas can also be passed through a coke bed in which the ammonia which has not reacted in the SCR-catalyst bed is removed from the gas.

In a process for injecting a radioactive sample of a substance into a reaction vessel, the sample is first enclosed in a first container in which it is irradiated, and then the first container with sample is placed in a second container which is separated from the reaction vessel by way of a closed valve. The second container is heated, and the sample is then conveyed out of the containers into the reaction vessel through the valve which is opened. The sample is enclosed within the first container by plugs or is frozen therein for which purpose the first container may possibly by put into intermediate storage in a storage container. An apparatus comprises the first container for receiving the sample, to be arranged and fixed within the second heatable pressure-resistant container which can be communicated with the reaction vessel through a valve.

In a process for making ferrous sulphate in granule form, ferrous sulphate heptahydrate is mixed with fine-grain brown coal or lignite having a low water content, in such an amount that the resulting mixture is pourable.

In order to improve the handling capability of red mud, it is mixed with fine-grain coal material such as brown coal or lignite in dust form, in a ratio by weight of between 0.5-10:1. The liquid present in the red mud is bound by the very fine coal admixed therewith so that the resulting mixture can be stored in a silo and even pneumatically conveyed, and the oily properties of the red mud are removed by the treatment. The mixture is particularly suitable for use in connection with the hydrogenating liquefaction of coal in which the red mud is used as a catalyst.
