Patent number: 8889933Abstract: A process can include making a bio-diesel, a bio-naphtha, and optionally bio-propane from a complex mixture of natural occurring fats & oils. The complex mixture can be subjected to a refining treatment for removing a major part of non-triglyceride and non-fatty acid components to obtain refined oils. The refined oils can be subjected to a fractionation step to obtain a substantially unsaturated liquid triglyceride part (phase L), and a substantially saturated solid triglyceride part (phase S). The phase L can transformed into alkyl-esters as bio-diesel by a transesterification. The phase S can be transformed into substantially linear paraffin's as the bio-naphtha by an hydrodeoxygenation. Fatty acids can be obtained from the phase S and transformed into substantially linear paraffin's as the bio-naphtha by hydrodeoxygenation or decarboxylation. Fatty acids soaps can be obtained from the phase S that are transformed into substantially linear paraffin's as the bio-naphtha by decarboxylation.Type: GrantFiled: November 5, 2013Date of Patent: November 18, 2014Assignee: Total Research & Technology FeluyInventors: Walter Vermeiren, Francois Bouvart, Nicolas Dubut

Patent number: 7964762Abstract: The present invention relates to a process for the producing propylene and ethylene from a light hydrocarbon stream comprising essentially ethane and butane. The process involves a non-catalytic cracking of ethane and normal-butane followed by a metathesis of ethylene and 2-butene to increase the propylene yield. Optionally the by-produced iso-butane is dehydrogenated and subsequently the produced iso-butene is converted to other valuable products like di-isobutylene, alkylate for gasoline blending tertiary-butyl-ethers, poly-isobutylene methyl-metacrylate or isoprene.Type: GrantFiled: May 16, 2007Date of Patent: June 21, 2011Assignee: Total Petrochemicals Research FeluyInventors: Francois Bouvart, Walter Vermeiren, Wolfgang Garcia, Alain Chepda

Patent number: 4715312Abstract: 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.Type: GrantFiled: August 6, 1986Date of Patent: December 29, 1987Inventor: Francois Bouvart
