    摘要: A process for the production of bio-oil from solid urban waste, comprising the following steps: a) subjecting said solid urban waste to liquefaction, obtaining a mixture including an oily phase consisting of bio-oil, a solid phase and an aqueous phase; b) subjecting the aqueous phase obtained in the liquefaction step a) to fermentation, obtaining a fermented biomass; c) feeding the fermented biomass obtained in the fermentation step b) to the liquefaction step a). The bio-oil (or bio-crude) thus obtained can be advantageously used in the production of biofuels which can be used as such or mixed with other motor vehicle fuels. Alternatively, this bio-oil (or bio-crude) can be used as such (biocombustible) or mixed with fossil combustibles (combustible oil, coal, etc.) for the generation of electric energy or heat.

    摘要: A process is described for the preparation of aromatic carbamates in which an organic carbonate in a stoichiometric quantity or in a quantity higher than the stoichiometric value is reacted with an aromatic amine operating in the presence of a carbamation catalyst, wherein this catalyst is selected from N,N-substituted carbamate complexes of zinc or copper. The process gives high yields and selectivity in the useful reaction product.
