Hydrocarbon compounds, particularly those boiling in the temperature range of between about 80° F. to about 1000° F., are produced by contacting a fatty material with at least one catalyst comprising cobalt and molybdenum on a zeolite support under hydrotreating conditions. Additional hydrotreating catalysts may also be used to further improve the properties of the hydrocarbon product. | 01-22-2009 |
20090266743 | THERMAL TREATMENT OF TRIGLYCERIDES - A triglyceride or a triglyceride/hydrocarbon combination can be heated to produce thermally treated feeds. The thermally treated feeds can then be contacted with a hydrotreating catalyst in a reaction zone. | 10-29-2009 |
20110047866 | REMOVAL OF IMPURITIES FROM OILS AND/OR FATS - Disclosed is a process for removing solids, metals, phosphorus compounds and other impurities from low quality triglyceride containing feedstock. The final treated triglyceride containing feedstock may be converted to fuel range hydrocarbons via hydrotreating process. | 03-03-2011 |
20110077436 | PRETREATMENT OF OILS AND/OR FATS - Disclosed are methods for pretreating triglyceride containing material prior to contacting with a hydrotreating catalyst to produce fuel range hydrocarbons without causing reactor fouling or catalyst plugging. | 03-31-2011 |
20110126449 | BLENDED FUEL COMPOSITION HAVING IMPROVED COLD FLOW PROPERTIES - There is provided a fuel composition comprising petroleum based component and a renewable based component, wherein at least 20% of the compounds in said petroleum based component having boiling point range equal or greater than the boiling point of said renewable based component. | 06-02-2011 |
20110237851 | THERMAL CRACKING OF IMPURITIES IN TRIGLYCERIDE FEEDSTOCK - A triglyceride or a triglyceride/hydrocarbon combination can be thermally cracked to remove its impurities in situ prior to be upgraded to fuel range hydrocarbon. This process allows the use of a variety of low cost feedstock and reduce reactor fouling tendency. The process also reduces the use of chemicals required for conventional clean up processes such as degumming. | 09-29-2011 |
20120000820 | HYDROPROCESSING PROCESS FOR THE IMPROVEMENT OF THE CATALYST LIFE - This invention relates to a hydroprocessing process for the improvement of catalyst life. Such inventive process is carried out with intermittent or discontinuous addition of a co-feed stream when hydroprocessing petroleum based feedstock or an oxygen containing feedstock. More specifically, it has been found that intermittent or discontinuous addition of the co-feed stream such as carbon monoxide, carbon dioxide, or their precursors to the hydrogen stream can reduce the long term deactivation, extend the life and increase run length of a cobalt/molybdenum hydrotreating catalyst. | 01-05-2012 |
20120017496 | HYDROPROCESSING PROCESS WITH IMPROVED CATALYST ACTIVITY - This invention relates to a hydroprocessing process with improved catalyst activity when hydroprocessing petroleum based feedstock or an oxygen containing feedstock. This invention also relates to a hydrotreating process with improved hydrodesulfurization (HDS) activity of a hydrotreating catalyst such as Co/Mo by co-feeding carbon monoxide or its precursors. Such inventive process confirms that adding a small amount of CO to H2 in a hydrotreater for a few days leads to an increase in product sulfur due to the inhibition of CO on the hydrotreating catalyst such as Co/Mo. However, it has been unexpectedly found that after the CO was removed from the hydrogen stream, product sulfur levels decreased to values below they were before CO addition which means the activity of the hydrotreating catalyst increased after the CO treatment. | 01-26-2012 |
20120022305 | HYDROCRACKING PROCESS FOR MAKING RENEWABLE DIESEL FROM OILS AND/OR FATS - Methods for producing C3-C30 hydrocarbons from fatty materials, such as triglyceride compounds, are provided. Hydrocarbon compounds, particularly those boiling in the temperature range of between about 80° F. to about 1000° F., are produced by contacting a fatty material, under hydrocracking conditions, with at least one catalyst comprising a Group VIII metal and a Group VIB metal on a acidic support. | 01-26-2012 |
20120157742 | PRODUCTION OF RENEWABLE FUELS - The present disclosure relates to a process for the conversion of oxygen-containing hydrocarbons into long-chain hydrocarbons suitable for use as a fuel. These hydrocarbons may be derived from biomass, and may optionally be mixed with petroleum-derived hydrocarbons prior to conversion. The process utilizes a catalyst comprising Ni and Mo to convert a mixture comprising oxygenated hydrocarbons into product hydrocarbons containing from ten to thirty carbons. Hydro-conversion can be performed at a significantly lower temperature than is required for when utilizing a hydrotreating catalyst comprising Co and Mo (CoMo), while still effectively removing sulfur compounds (via hydrodesulfurization) to a level of 10 ppm (by weight) or less. | 06-21-2012 |
20130172650 | UPGRADING LIGHT OLEFINS - Methods and systems relate to upgrading light olefins, such as ethylene, propylene and butylenes, diluted in a gas mixture, such as refinery fuel gas. The upgrading yields products in a gasoline, distillate, lube oil or wax range without requiring purification or compression of the gas mixture prior to feeding the gas mixture to a reactor. In operation, the mixture contacts a solid oligomerization catalyst, such as silica supported chromium, within the reactor. This contact occurs at a first temperature suitable to produce oligomers that are formed of the olefins and adsorb on the catalyst in liquid or solid phases. Next, heating the catalyst to a second temperature higher the first temperature desorbs the oligomers that are recovered and separated into the products. | 07-04-2013 |
20140213836 | THERMAL CRACKING OF IMPURITIES IN TRIGLYCERIDE MIXTURES - A heated petroleum-derived hydrocarbon is contacted with a triglyceride feed in a thermal cracking zone to decompose and remove impurities prior to hydrotreating the mixture to fuel range hydrocarbon. This process allows the use of a variety of low cost triglyceride feeds while reducing fouling of process equipment and catalyst. The process also reduces the use of chemicals required for conventional degumming of triglyceride feeds. | 07-31-2014 |
