A process is provided for the production of hydrocarbons from synthesis gas wherein the synthesis gas is fed to a reactor in which a catalyst acts on the feed at a temperature of between 160&#xb0; C. and 400&#xb0; C. and a pressure of between 1 bar and 5 bar. The feed includes a compound containing one or both nitrogen and phosphorus added to the reactor with the synthesis gas. The compound containing nitrogen typically constitutes at least 1 vol % and preferably of the order of 4 to 20 vol % or more of the feed. The carbonaceous gas may be carbon monoxide with a ratio of hydrogen to carbon monoxide in the synthesis gas of from 0.5:1 to 5:1. The catalyst is preferably a supported cobalt catalyst and may be modified with a promoter. The process produces an enhanced proportion of olefins, in the hydrocarbons produced.

A process is described for the production of one or more of linear nitriles, amides and formamides which includes reacting a nitrogen containing compound, such as ammonia or NO, and a synthesis gas over a catalyst at a temperature of between 160&#xb0; C. and 400&#xb0; C. and a pressure of between 1 bar and 50 bar. A further process for the production of one or more of linear phosphorous containing compounds is also described, which includes reacting a phosphorous containing compound, such as a phosphine, and a synthesis gas over a catalyst at a temperature of between 160&#xb0; C. and 400&#xb0; C. and a pressure of between 1 bar and 50 bar. A supported cobalt, iron, ruthenium or rhodium catalyst or an unsupported (bulk) promoted iron catalyst, modified with a promoter is used. The synthesis gas is a mixture of hydrogen and carbon monoxide, in a ratio from 0.5:1 to 5:1; or a mixture of hydrogen and carbon dioxide; or a mixture of water and carbon monoxide. The suppression of the formation of oxygenates in the process is a feature of the invention and oxygenates may even be included in the feed to become converted to corresponding nitrogen containing compounds in the process.

A process for making a fiber composite involving: (a) providing a natural fiber; (b) providing a matrix material produced by a radical polymerization reaction of: (i) a monomer selected from the group consisting of ring opening products of epoxidized fatty compounds with olefinically unsaturated carboxylic acids, and (ii) a comonomer selected from the group consisting of olefinically unsaturated carboxylic acids; (c) providing a radical initiator; and (d) conducting the radical polymerization reaction of (i) and (ii) in the presence of the natural fiber so that the matrix material envelops the natural fiber, thus producing the fiber composite.
