Abstract: The present invention relates to a process for the production of high value chemicals, preferably including at least ethylene and propylene, by steam cracking a mixture of non-cyclic paraffin stream (A) comprising at least 90% of components having at least 12 carbon atoms, with either a mixture of hydrocarbons having from 3 to 4 carbon atoms or a mixture of hydrocarbons comprising at least 90% of components having a boiling point ranging from 15° C. to 200° C.

Abstract: The invention relates to Process of catalytic conversion by hydrocracking of paraffinic and naphthenic hydrocarbons from a naphtha feedstock to propane, the process comprising the steps of providing a naphtha feedstock containing one or more paraffin comprising 4 to 10 carbon atoms and no olefins; and contacting said naphtha feedstock with a catalyst composition in the presence of hydrogen in a reaction zone under hydrocracking conditions; wherein the catalyst composition consists of one or more zeolite catalysts comprising acid 10-membered ring channels containing no added metals.

Abstract: The invention relates to a process of catalytic conversion by dehydro steam cracking of paraffinic and naphthenic hydrocarbons from a naphtha feedstock to propylene in presence of steam, comprising the following steps: a. providing a naphtha feedstock (1) containing one or more paraffins and/or naphthene's comprising 4 to 10 carbons atoms; b. contacting (3) said naphtha feedstock (1) with a catalyst composition in the presence of steam in a reaction zone under dehydro steam cracking conditions at a temperature of at most 650° C., resulting in the production of an effluent (5); c. recovering the effluent of step b) and separating (7) it into a converted fraction (9) and an unconverted fraction (11), wherein the unconverted fraction (11) comprises propane and one or more paraffins comprising 4 to 10 carbons atoms; and d.

Abstract: Use of fatty acids produced from a complex mixture of natural occurring oils & fats and/or of triglycerides deriving from said complex mixture as the feedstock of a steamcracker, by mixing the fatty acids with steam in a steam/feedstock ratio of at least 0.2 kg per kg, a coil outlet temperature of at least 700° C. and an coil outlet pressure of at least 1.2 bara in order to obtain cracking products including bio-ethylene, bio-propylene, bio-butadiene, bio-isoprene, bio-cyclopentadiene and bio-piperylenes, bio-benzene, bio-toluene, bio-xylene and bio-gasoline.

Abstract: A process (or steam cracking a hydrocarbon feedstock containing olefins to provide increased light olefins in the steam cracked effluent, the process comprising passing a first hydrocarbon feedstock containing one or more olefins through a reactor containing a crystalline silicate to produce an intermediate effluent with an olefin content of lower molecular weight than that of the feedstock, fractionating the intermediate effluent to provide a lower carbon fraction and a higher carbon fraction, and passing the higher carbon fraction, as a second hydrocarbon feedstock, through a stream cracker to produce a steam cracked effluent.
