Abstract: In a novel process for methanol production from low quality synthesis gas, in which relatively smaller adiabatic reactors can be operated more efficiently, some of the inherent disadvantages of adiabatic reactors for methanol production are avoided. This is done by controlling the outlet temperature in the pre-converter by rapid adjustment of the recycle gas, i.e. by manipulating the gas hourly space velocity in the pre-converter.

Abstract: A method for the preparation of a catalyzed monolithic body or a catalyzed particular filter. The method includes the step of suctioning a sol-solution containing catalytically active material and metal oxide catalyst carriers or precursors thereof into pores of a monolithic substrate, solely by capillary forces and without the application of vacuum or pressure.

Abstract: The invention relates to the production of synthesis gas by means of particularly a series arrangement of heat exchange reforming and autothermal reforming stages, in which the heat required for the reforming reactions in the heat exchange reforming stage is provided by hot effluent synthesis gas from the autothermal reforming stage. More particularly, the invention relates to optimisation of the operation and control of an arrangement of heat exchange reforming and autothermal reforming stages and introduction of an additional waste heat boiler.

Abstract: In a process for the production of higher alcohols, i.e. C4+ alcohols, from syngas, the syngas is first reacted in a heterogeneous alcohol pre-converter (A) using an alcohol synthesis catalyst, whereby methanol as the main product in a concentration corresponding to or close to the equilibrium concentration is produced. Then the effluent from the pre-converter is mixed with unconverted wet recycle gas and reacted in a heterogeneous reactor for higher alcohols synthesis (B) containing a higher alcohols synthesis catalyst, and finally the effluent from the reactor for higher alcohols synthesis is separated into (i) unconverted syngas, which is recycled to the higher alcohols synthesis reactor, (ii) methanol and light alcohols, which are recycled to the higher alcohols synthesis reactor, and (iii) the final product consisting of higher alcohols.
