Patent number: 8373015Abstract: Catalytic methods for the production of saturated hydrocarbons with 2 to 5 carbon atoms per molecule by conversion of small hydrocarbon halides and/or hydrogenation of carbonaceous material are disclosed that result in high yield of saturated C2 to C5 hydrocarbons at reduced corrosion of the reactors and in good lifetime of the catalyst. The methods are performed in the presence of a Lewis acid comprising catalyst and in the absence of oxygen or oxygen containing compounds, whereby an upper limit of at most 50 parts per million mass of oxygen or oxygen containing compounds can be tolerated.Type: GrantFiled: March 19, 2007Date of Patent: February 12, 2013Assignee: ETH ZürichInventors: Jan Wendelin Stark, Neil Osterwalder

Patent number: 8221706Abstract: Apparatuses for processing a hydrocarbonaceous feedstock flows are provided. In one aspect, the method includes providing two or more hydroprocessing stages disposed in sequence, each hydroprocessing stage having a hydroprocessing reaction zone with a hydrogen requirement and each stage in fluid communication with the preceding stage. A hydrogen source is provided substantially free of hydrogen from a hydrogen recycle compressor. The hydrocarbonaceous feedstock flow is separated into an portions of fresh feed for each hydroprocessing stage, and the first portion of fresh feed to the first hydroprocessing stage is heated. The heated first portion of fresh feed is supplied with hydrogen from the hydrogen source in an amount satisfying substantially all of the hydrogen requirements of the hydroprocessing stages to a first hydroprocessing zone. The unheated second portion of fresh feed is admixed with effluent from previous stage to quench the hot reactor effluent before entering a second stage.Type: GrantFiled: June 30, 2009Date of Patent: July 17, 2012Assignee: UOP LLCInventors: John A. Petri, Vedula K. Murty, Peter Kokayeff
