Publication number: 20150080624Abstract: A process and apparatus for producing hydrocarbon oil from the thermal decomposition of waste plastics in a continuous process which comprises melting of a waste plastic feedstock into an auger assisted melt reactor to remove chlorine and organics contained in the waste plastic, and transferring the melted waste plastic into an heated screw pyrolysis reactor which includes a transitional metal heat transfer medium. The hydrocarbon gas from the pyrolysis reactor is fed into a vessel containing metal trays for a second decomposition which is connected with an alkali treatment 2-step process gas reactor to remove acidic gases, and any inorganic solids. The hydrocarbon gases are separated by three separate condensers. The hydrocarbon fraction of the first condenser is recycled back into the pyrolysis reaction for further thermal treatment, and the hydrocarbon fractions are collected in the remaining condensers.Type: ApplicationFiled: September 15, 2014Publication date: March 19, 2015Inventors: Stephen B.

Patent number: 8957269Abstract: The invention relates to a method of producing olefinic monomers for the production of a polymer. The invention particularly relates to the production of tall oil-based biopolymers, such as polyolefins. In the stages of the method bio oil, with a content of over 50% of fatty acids of tall oil and no more than 25% of resin acids of tall oil, and hydrogen gas are fed into a catalyst bed (7); the oil is catalytically deoxygenated in the bed by hydrogen; the flow exiting the bed is cooled down and divided into a hydrocarbon-bearing liquid phase (10) and a gas phase; and the hydrocarbon-bearing liquid (13) is subjected to steam cracking (4) to provide a product containing polymerizing olefins. The deoxygenation in the bed can be followed by a catalytic cracking or, with a suitable catalyst, the deoxygenation and cracking can be simultaneous. The separated hydrogen-bearing gas phase can be circulated in the process.Type: GrantFiled: January 29, 2010Date of Patent: February 17, 2015Assignee: Stora Enso OyjInventors: Ali Harlin, Tapani Penttinen, Jari Räsänen, Olli Aaltonen

Patent number: 8927796Abstract: This invention discloses a process for making high viscosity index lubricating base oils having a viscosity index of at least 110 by co-feeding a ketone or a beta-keto-ester feedstock with a lubricant oil feedstock directly to a hydrocracking unit to produce a hydrocracked stream. Then at least a portion of the hydrocracked stream is treated under hydroisomerization conditions to produce a high viscosity index lubricating base oil. The process may involve bypassing a hydrotreating or hydrofinishing step, which may result in improved efficiency and economics in producing high viscosity index lubricating base oils.Type: GrantFiled: September 13, 2012Date of Patent: January 6, 2015Assignee: Chevron U.S.A.

Patent number: 8927797Abstract: The method produces a hydrocarbonaceous fluid (a liquid mixture of hydrocarbons, or in other words a mixture of hydrocarbons which is liquid at ambient room temperature and atmospheric pressure), which functionally is a liquid hydrocarbon fuel, from a feed of waste plastic. The method can comprise the steps of: (step 1) melting a feed of substantially solid waste plastic in an aerobic atmosphere (for instance, air) whereby a waste-plastic melt is produced; (step 2) distilling at least a portion of the waste-plastic melt whereby a hydrocarbonaceous distillate is produced; and (step 3) collecting the hydrocarbonaceous distillate. That distillate is generally referred to above as a condensate. The method can include the step of comminuting the feed of substantially solid waste plastic into pieces substantially no greater than about 1.5 cm2 prior to step 1. The method can also include the step of adding an effective amount of a cracking catalyst to the waste plastic prior to step 2.Type: GrantFiled: February 2, 2011Date of Patent: January 6, 2015Assignee: Natural State Research, Inc.Inventor: Moinuddin Sarker

Patent number: 8907150Abstract: A method of producing from a biomass mesitylene-isopentane fuel is provided. A biomass may be fermented to form acetone. The acetone is converted in a catalytic reactor to mesitylene and mesityl oxide. The mesitylene is separated in a phase separator and the organic face containing mesityl oxide is sent to a dehydration reactor, then to a demethylation reactor, and finally to a hydrogenation reactor from which isopentane is recovered. This isopentane is then mixed with the mesitylene to form the final mesitylene-isopentane fuel. The catalytic reaction with acetone employs catalysts of either niobium, vanadium or tantalum.Type: GrantFiled: August 25, 2011Date of Patent: December 9, 2014Assignee: Swift Fuels, LLCInventor: John J.
