Process for the production of bio-naphtha from complex mixtures of natural occurring fats and oils

Disclosed is a method for steam-cracking naphtha, according to which a charge of hydrocarbons containing a portion of paraffinic naphtha, which is modified by adding a combination of a first component containing a portion of gasoline and a second component containing a portion of at least one hydrocarbonated refinery gas, and a paraffin-rich change containing at least one paraffin selected among propane, butane, or a mixture thereof are fed through a steam cracker in the presence of vapor. Also disclosed is a hydrocarbon composition suitable for steam cracking, containing a portion of a paraffinic naphtha, which is modified by adding a combination of a first component containing a portion of gasoline and a second component containing a portion of at least one hydrocarbonated refinery gas and a paraffin-rich charge containing at least one paraffin selected among propane, butane, or a mixture thereof.

Steam-cracking of modified naphtha

This invention relates to a craft comprising a hull capable of floating on water, the aft part of said hull constituting the hollow space of a navigation cabin, and a forward end part which constitutes a removable stem distinct from the hull, capable of being connected to and detached from the forward part of the hull and which, in the configuration in which it is detached from the forward part of the hull, is capable of being positioned above the navigation cabin to constitute a volume, preferably a living room. The craft is provided with natural means of communication from the volume defined by the removable stem with the outside of this stem, so as, in the configuration in which the stem is connected to the forward part of the hull, to allow natural flow of the excess water contained in the stem volume, out of the stem volume. One application of the invention is the production of an inexpensive combined boat/caravan.
