Process for the production of isoparaffins

A process for the production of methanol by reacting a gaseous mixture comprising hydrogen and carbon monoxide in the presence of a catalyst composition in the form of a fluidized bed whilst cooling, characterized in that the catalyst composition is present in a plurality of interconnected fluidized bed sections whereby each section is cooled by at least one heat exchanger and whereby the temperature in the highest section is reduced to below the highest temperature in a lower section.

Process for the production of methanol

A process for the production of methanol by reacting a gaseous mixture comprising hydrogen and carbon monoxide in the presence of a catalyst composition in a fluidized bed while cooling, characterized in that the reaction is carried out in a plurality of fluidized catalyst bed reactors in series with interstage removal of methanol from the reaction mixture.

Catalytic partial oxidation process for converting natural gas to synthesis gas in which the process operates at high temperature T&gt;1000.degree. C. with entrained catalyst. Fine catalyst particles are transferred by means of a gas stream to a burner device which effects a rapid and intensive mixing of this gas stream with the reactants, e.g., natural gas, oxygen and steam. The catalyst entrained by the product gas stream is separated from this stream and recycled to the reactor.
