The present invention relates to a process for the production of olefinic compounds that can be used for the production of detergents, additives, lubricants and/or plastic materials, or components which can be used in the field of oil explorations and productions, and a hydrocarbon fuel or a fraction thereof, which comprises subjecting a mixture of glycerides having at least one unsaturated hydrocarbon chain, to metathesis reaction and, after separating the olefinic mixture obtained, effecting a hydrodeoxygenation and subsequently hydroisomerization process, so as to obtain the hydrocarbon fuel or a fraction thereof.

Integrated process for the production of bio-oil from sludge coming from a wastewater purification plant comprising the following steps: (a) sending wastewater to said purification plant obtaining sludge; (b) subjecting the sludge obtained in said step (a) to liquefaction, obtaining a mixture Including an oily phase consisting of bio-oil, a solid phase and an aqueous phase; (c) sending the aqueous phase obtained in said step (b) to said purification plant. The bio-oil (or 'bio-crude') thus obtained can be advantageously used in the production of bio-fuels which can be used as such, or in a mixture with other automotive fuels. Otherwise, said bio-oil (or 'bio-crude') can be used as such (bio-fuel), or in a mixture with fossil fuels (combustible oil, coal, etc.), for the generation of electric energy or heat.

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.

A process for producing bio-oil from municipal solid waste, the process including: a) liquifying municipal solid waste, to obtain a mixture containing an oily phase containing bio-oil, a solid phase, and a first aqueous phase; b) treating the first aqueous phase from a) with an adsorbing material, to obtain a second aqueous phase; c) fermenting the second aqueous phase from b), to obtain a biomass; d) subjecting the biomass obtained in c) to the liquification a). The bio-oil obtained is advantageously used in the production of biofuels for motor vehicles or for the generation of electric energy or heat.

The cultivation of heterotrophic and phototrophic micro-organisms is integrated for the production of bio-oil for biofuels, wherein the overall algal suspension produced is first thickened, with recirculation of the excess water to cultivation containers, and then thermally treated at a high temperature. After cooling, a bio-oil phase is recovered together with a suspension rich in soluble carbohydrates and proteins which forms a nutritional/energy source for heterotrophic micro-organisms.

A process to efficiently remove sulfur compounds from a hydrocarbon stream in a refinery operation includes the production and recycle of hydrogen from the sulfur compounds. The sulfur compounds present in the hydrocarbon cut are converted to hydrogen sulphide which is split to hydrogen and sulfur in a non-thermal plasma reactor.

The present invention relates to a process for producing large amounts of 7.beta.-(4-carboxybutanamido)-cephalosporanic acid acylase ('GA') enzyme, which process consists in growing, under suitable culture conditions, a recombinant Escherichia coli K12 strain and subsequently extracting the enzyme from the resulting culture. Enzyme production is controlled by a particular expression system which can be induced by corn-steep liquor, an extremely low cost component of the culture medium. The enzyme can be used in the enzymatic preparation of 7-amino-cephalosporanic acid by starting from 7.beta.-(4-carboxybutanamido)-cephalosporanic acid.
