A process is described for the production of hydrocarbons with a high octane number starting from mixtures essentially consisting of n-butane and isobutane (such as for example field butanes) comprising a skeleton isomerization section, a dehydrogenation section of paraffins, a selective hydrogenation section of butadiene, two conversion sections of olefins, in which the isobutene is firstly selectively transformed by means of dimerization and/or etherification, followed by the linear butenes by means of alkylation, in order to obtain, by joining the products of the two conversion sections, a product having excellent motoristic properties (octane number, volatility and distillation curve).

Process for the production of hydrogen consisting in subjecting a solid to oxidation and treating, in a different zone, the oxidized form thus produced with a reducing stream, preferably a hydrocarbon.

Process for the production of hydrogen

Process for the production of synthesis gas, by means of catalytic partial oxidation or autothermal reforming of light hydrocarbons, which comprises partially oxidizing the hydrocarbon with oxygen coming from the reduction of at least one metal oxide selected from hexavalent chromium oxide, supported on an inert carrier and modified with an alkaline and/or earth-alkaline metal, and metal oxides capable of autonomously sustaining the catalytic partial oxidation reaction by means of redox cycles.

Process for the production of synthesis gas

Liquid mixture suitable as gasoline

A catalytic system and process for producing mixtures of methanol and higher alcohols from synthesis gas, the catalytic system comprising zinc, chromium, copper, one or more alkaline metals, and possibly one or more metals chosen from molybdenum, manganese, lanthanium, cerium, aluminium, titanium and vanadium, either all or only part of said elements being chemically bonded to oxygen and/or together.

Catalytic system for producing mixtures of methanol and higher alcohols

A process for the production of a mixture of methanol and higher alcohols of 'fuel grade' from CO and H.sub.2. To reduce the water content in the mixture coming from the synthesis reactor of the synthesis of the alcohols, the reaction product is cooled down and is fed to a secondary reactor wherein the conversion reaction

A method is disclosed for obtaining high-purity ethylene glycols in which the improvement consists in reducing the oxygen-containing organic impurities by treating their aqueous solutions as obtained during the processing of ethylene oxide with a solution of an alkali metal borohydride, sodium borohydride being preferred. A definitely alkaline environment is preferred. Ethylene glycols can thus be obtained which are particularly suitable for use in the fibre-manufacturing industry. Such glycols have extremely low UV-absorbance values.
