Patent number: 9005429Abstract: The present invention relates to hydrocarbons and particularly to the manufacture of hydrocarbon components suitable as aviation fuels or jet fuels and as blending stocks for aviation fuels. The process comprises the stages, wherein in the first stage an oil feed of biological origin and hydrogen gas are subjected to conditions sufficient to effect hydrodeoxygenation in the presence of a hydrodeoxygenation catalyst to yield n-paraffins; in the second stage the n-paraffins and hydrogen gas are subjected to conditions sufficient to effect isomerization in the presence of an isomerization catalyst to yield isoparaffins and separating fractions; and recycling the fraction boiling at a temperature above 200° C. under atmospheric pressure obtained from the second stage to reisomerization, where isomerization is effected in the presence of an isomerization catalyst.Type: GrantFiled: June 30, 2009Date of Patent: April 14, 2015Assignee: Neste Oil OyjInventors: Varpu Markkanen, Petri Lindqvist, Elina Harlin, Pekka Aalto, Jukka Myllyoja, Ville Alopaeus

Patent number: 7604794Abstract: The present invention relates to an active and selective zeolite catalyst having MTT structure that is useful in skeletal isomerisation of light olefins. The method for the manufacture of the zeolite catalyst having MTT structure comprises the steps of a) preparing of a gel mixture capable of forming crystalline material, and the mixture comprising sources of alkali or alkaline earth metal (M), of an oxide of a trivalent element (X), of an oxide of a tetravalent element (Y), water and a directing agent (R), and the mixture having a composition, in terms of molar ratios, within the given ranges; b) maintaining the mixture under sufficient conditions, including a temperature of from about 100° C. to about 250° C., under dynamic mode of stirring until crystals of the material are formed, recovering the material; and c) removing the directing agent (R) partly or totally with a calcination procedure.Type: GrantFiled: March 9, 2004Date of Patent: October 20, 2009Assignee: Neste Oil OyjInventors: Marja Tiitta, Elina Harlin, Jaana Makkonen, Narendra Kumar, Dmitry Yu Murzin, Tapio Salmi

Patent number: 7329788Abstract: Process for producing gasoline components. The process comprises feeding a fresh olefinic hydrocarbon feedstock to a reaction zone, in which its structure is first isomerized. The isomerized hydrocarbon is drawn out of the first reaction zone and conducted to a second reaction zone, where the isomerized hydrocarbon is dimerized. The dimerized reaction product is drawn out of the second reaction zone and separated from the flow in a separation zone. Because there are more isoolefins present in the dimerization unit feed, more isoolefin dimers useful as fuel components can be produced.Type: GrantFiled: December 22, 2003Date of Patent: February 12, 2008Assignee: Neste Oil OyjInventors: Marja Tiitta, Elina Harlin, Antti Pyhälahti

Publication number: 20070006523Abstract: The invention relates to chemical industry and is directed to the production of middle distillate from vegetable oils. In the first step of the production method, the fatty acids or triglycerides of said vegetable oils are hydrogenated to give n-paraffins, and in the second step, the n-paraffins are catalytically converted to paraffins with branched chains. Using this process having two steps, a high-quality middle distillate useful as a component of diesel fuels without any particular specifications may be produced.Type: ApplicationFiled: June 30, 2006Publication date: January 11, 2007Applicant: Neste Oil OyjInventors: Jukka Myllyoja, Pekka Aalto, Elina Harlin
