Abstract: Gases of various origins which contain carbon monoxide and dioxide and hydrogen, for example the gases obtained by steam reforming or the rich gas process, refinery gases or coal gasification gases are methanized on a nickel catalyst. The object of this reaction is to obtain methane or gases which can be substituted for natural gas. To produce the catalyst, the compound Ni6Al2(OH)16.CO3.4H2O is obtained from aqueous solution. The catalyst is obtained from this compound after drying, calcination and subsequent reduction in a stream of hydrogen, whilst maintaining very specific temperature gradients between the drying stage and the calcination stage.

Abstract: The present invention relates to a process for producing expandable styrene polymers containing graphite particles, which process comprises polymerizing styrene, optionally together with 20 percent by weight of comonomers, based on the weight of polymers, in aqueous suspension in the presence of graphite particles having a mean particle size of from 1 to 50 microns with addition of peroxide initiators and adding a blowing agent before, during or after the polymerization. Claimer are also particulate expandable styrene polymers containing graphite particles having a mean particle size of from 1 to 50 microns, wherein the graphite particles are homogeneously distributed in the styrene polymer and the styrene polymer is in the form of round beads having a mean diameter in the range from 0.2 to 2 mm. The invented expandable styrene polymers are used in the production of foam materials having density of about 5 to 35 g/l.

Abstract: The invention relates to expandable styrene polymers containing a) a styrene polymer, b) and at least one carbon dioxide absorber, mixed or copolymerized with the above, in an amount of from 0.01 to 50% by weight, based on the sum of a) and b), and c) a blowing agent or blowing agent mixture in an amount of from 0.5 to 12% by weight, where the blowing agent or blowing agent mixture comprises c1) from 10 to 100% by weight of carbon dioxide and c2) from 0 to 90% by weight of at least one further blowing agent. The invention furthermore relates to the styrene polymers containing a carbon dioxide absorber, to the styrene polymer foams obtainable from the expandable styrene polymers, and to an improved process for impregnating styrene polymers with carbon dioxide-containing blowing agents or blowing agent mixtures.
