    Abstract: Method for producing synthesis gas for methanol production The present invention relates to a method for producing synthesis gas from a hydrocarbon containing feed, which synthesis gas is particularly suitable for subsequent use in methanol production. In this method, a hydrocarbon containing feed, particularly natural gas (100), is subjected to catalytic partial oxidation (CPO) (2), followed by the water gas shift (WGS) (4) reaction of a part of the reformed feed. At least part of the shifted feed is then subjected to hydrogen purification, preferably by pressure swing adsorption (PSA) (5) to obtain pure hydrogen (108), which hydrogen is subsequently combined with the remaining parts of the feeds to yield synthesis gas particularly suitable for methanol synthesis. The recombined stream preferably has an R ratio, being the molar ratio (H2−CO2)/(CO+CO2), in the range 1.9-2.2 and preferably about 2. The invention further relates to a method for producing methanol from a hydrocarbon containing feed, wherein first synthesis gas is obtained according to the method of the invention, which synthesis gas is further used to produce methanol.

    Abstract: Method for producing synthesis gas for methanol production The present invention relates to a method for producing synthesis gas from a hydrocarbon containing feed, which synthesis gas is particularly suitable for subsequent use in methanol production. In this method, a feed (100) is divided into two streams, wherein one stream is subjected to catalytic partial oxidation (CPO) (2) and the other stream is subjected to steam reforming (5) followed by a water gas shift reaction (51). The two streams are then recombined and can be used further in methanol synthesis (6). The recombined stream preferably has an R ratio, being a molar ratio (H2−C02)/(CO+C02), in the range of 1.9-2.2 and preferably about 2. The invention further relates to a method for producing methanol from a hydrocarbon containing feed, wherein first synthesis gas is obtained according to the method of the invention, which synthesis gas is further used to produce methanol. Also, the invention relates to a method of adapting an existing methanol plant to the methanol production process of the invention.

    Abstract: A process for preparing block copolymers is disclosed, wherein a living polymer of a diene is formed which carries at least one negatively charged diene unit in the end position, from 1 to 100 monomer units of styrene or a ring-substituted styrene derivative is polymerized on each living polymer anion site, and then a polymer block of Alpha -methylstyrene units is formed by polymerization of Alpha -methylstyrene. The cross-over reaction from the polymer block having the dienyl anion in the end position to the Alpha -methylstyrene is facilitated by the presence of the styrene or styrene derivative. The block copolymers can be employed for numerous applications wherein synthetic rubber is used, such as in bicycle tires, footwear, flooring, adhesives, coatings and elastomeric fibers.
