Shaped carbon bodies, suitable for use in nuclear reactors as moderators, reflectors or heat carriers, are prepared from graphitic carbon, either by mixing it with a deuterated heavy hydrocarbon material in which the atomic ratio of deuterium to carbon is at least 1.3 to 1 and compressing the ...
Method of preparation of ethylene copolymers suitable for manufacturing films or pipes so characterized that for the initiation of polymerization of ethylene and 1-alkene monomer a substantially innovated catalyst system containing silyl chromate compound is used. The principle of synthesis of the catalyst...
The olefinic compound suitably contains 2 to 60 carbon atoms and may be a C 3 to C 40 alkene which may be substituted with a hydroxyl group or halogen atom, e.g. propylene, allyl alcohol or allyl chloride. The hydroperoxide may contain 3 to 20 carbon atoms, e.g. tertbutyl- or tert...
摘要: Method of separating a gaseous alkene from a gaseous alkane by a pressure swing adsorption process unit alone or in combination with the distillation column wherein the alkene is preferentially adsorbed onto a bed of 4A zeolite at a temperature of about 50 DEG to about 200 DEG C.收藏...
