An improved catalyst suitable for use in the production of hydrocarbons from the synthesis gas comprises an iron-containing Fischer-Tropsch catalyst, a zeolite and at least one metal selected from the group consisting of ruthenium, rhodium, platinum, palladium, iridium, cobalt and molybdenum. This catalyst gives a high CO conversion and hydrocarbons enriched with C.sub.5.sup.+ gasoline fraction.

Catalyst for the production of hydrocarbons from the synthesis gas

In a process for heat treatment, highly hygroscopic coal, with a low carbon content and large equilibrium moisture, is rapidly heated with hot gas at a rate of temperature rise of at least 100.degree. C./min up to a final heating temperature in the range of 300.degree.-500.degree. C., and is then rapidly cooled at a rate of temperature drop of at least 50.degree. C./min to 250.degree. C. or below. As the hot gas, an inert gas whose oxygen concentration is not higher than 4% by volume is employed. The hot gas is either caused to contain not less than 20% by volume of steam or composed solely of the steam.

Process for heat treatment of coal

A catalyst for the selective catalytic reduction of nitrogen oxides by the use of ammonia as a reducing agent composed of a catalytically active constituent on a carrier having a honeycomb or parallel plate structure, the carrier being prepared from a slurry of crystallized calcium silicate prepared by mixing silicic acid and lime and heating the mixture under pressure, the calcium silicate having the structure of xonotrite and the formula 6 CaO.6 SiO.sub.2. H.sub.2 O.

Catalyst for selectively reducing nitrogen oxides from oxygen-containing

A catalyst for selective catalytic reduction of nitrogen oxides by use of ammonia as a reducing agent is prepared by mixing a silicic acid material with a lime material, heating the mixture under pressure to form a slurry of calcium silicate crystals, forming the slurry into a carrier, and then allowing the carrier to carry a catalytically active ingredient.
