    摘要: There is an absorbent mixture usable for the removal of sour gases from gas mixtures. The mixture has at least one organic base having a pKb (in water) less than or equal to 3.2; at least one alcoholic solvent of general formula R(OH)n having a boiling temperature above or equal to 100° C. at ambient pressure, wherein R is a linear or branched saturated alkyl group having a number of carbon atoms between 2 and 20 and n is a whole number varying between 1 and 20; an aprotic polar solvent having a dielectric constant E at 25° C. greater than or equal to 30, a viscosity μ at 25° C. less than or equal to 14 cP, preferably less than or equal to 12 cP; and a boiling temperature at normal pressure equal to or above 130° C. There is also a process for the removal of sour gases using the absorbent mixture.

    摘要: System and relative process for the complete and high-productivity hydroconversion of heavy oils essentially consisting of a solid accumulation reactor and a stripping section of the conversion products outside or inside the reactor itself.In particular, the system proposed consists of a solid accumulation hydroconversion reactor in which the solids deriving from and generated by the feedstock treated (metals in the form of sulphides and coke) are accumulated, up to very high levels, and a hot gas stripping section of the reaction liquid, designed in relation to the type of reactor adopted, for the direct and continuous removal of the conversion products, including high-boiling products.

    摘要: There is a process for high sulfur content copolymer preparation having the step of reacting sulfur in solid form with at least one crosslinker selected from organic compounds having at least a double or triple bond in the presence of at least one catalyst selected from dithiocarbamates, mercaptobenzothiazoles, xanthates, thiophosphates, at a temperature ranging from 110° C. to 180° C.
    The high sulfur content copolymer, depending on the glass transition temperature, can be of elastomeric or thermoplastic type and can be advantageously used in different applications. In case of an elastomeric-type high sulfur content copolymer, the copolymer can be advantageously used in different applications such as, for example, thermal insulation, conveyor belts, transmission belts, flexible tubes, elastomeric tire compositions. In case of a thermoplastic-type high sulfur content copolymer, the copolymer can be advantageously used, as such or in a mixture with other (co)polymers (for example, styrene, divinylbenzene), in different applications such as, for example, packaging, electronics, household appliances, computer cases, CD cases, kitchen, laboratories, offices and medical items, in building and construction.
