    Abstract: A process for removing chemical oxygen demand, which realizes the deep COD treatment by the combination of metal salt and hydrogen peroxide and then by an ozone containing gas with hydrogen peroxide or ultraviolet radiation with hydrogen peroxide. It features using less metal salt and hydrogen peroxide, having less ozone gas residual and being more suitable for industrialization.

    Abstract: A chemical blowing agent for foaming a thermoplastic polymer, for example PVC plastisol or a polymer resin in an extrusion process, said chemical blowing agent comprising a functionalized particulate bicarbonate containing at least one polyoxyalkylene additive, preferably excluding an exothermic blowing agent. The polyoxyalkylene additive may be selected from the group consisting of polyoxyalkylenes, any derivative thereof, salts thereof, and any combinations thereof. The particulate bicarbonate may be preferably functionalized by spray-coating, extrusion or co-grinding with at least one polyoxyalkylene additive. The functionalized particulate bicarbonate may comprise 50 wt % to less than 100 wt % of the bicarbonate component, and 0.02-50 wt % of the additive. The functionalized particulate bicarbonate may further comprise 0.1-5 wt % silica. A foamable polymer composition comprising such chemical blowing agent. A process for manufacturing a foamed polymer, such as foamed PVC, comprising shaping and heating the foamable polymer composition, and a foamed polymer obtained by such process.

    Abstract: The present invention concerns a process for manufacturing a porous carbonaceous monolith structure comprising the steps of (i) introducing a precursor material comprising particles comprising a halogenated polymer having a melting point in a mold; (ii) forming a shaped body comprising aggregates of the particles of the precursor material, by concurrently applying to the precursor material a pressure P ranging from 10 to 300 bars when the halogenated polymer is a vinylidene chloride homopolymer and from 10 to 150 bars when the halogenated polymer differs from a vinylidene chloride homopolymer, and maintaining the precursor material at a temperature T1 ranging from T1,min=20° C. to T1,max=Tm−50° C. wherein Tm is the melting point of the halogenated polymer, and; (iii) optionally cooling then demolding the shaped body; (iv) introducing the shaped body in a furnace; (v) causing the pyrolysis of the halogenated polymer in the furnace until the porous carbonaceous monolith structure is obtained.
