  • Publication number: 20130172650
    Abstract: 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.

  • Publication number: 20120157742
    Abstract: 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.

  • Publication number: 20120095274
    Abstract: Technologies to convert biomass to liquid hydrocarbon fuels are currently being developed to decrease our carbon footprint and increase use of renewable fuels. Since sugars/sugar derivatives from biomass have high oxygen content and low hydrogen content, coke becomes an issue during zeolite upgrading to liquid hydrocarbon fuels. A self-sustainable process was designed to reduce the coke by co-feeding sugars/sugar derivatives with the paraffin products from hydrogenation of sugars/sugar derivatives. Paraffins without complete conversion result in products with less aromatics and relatively low density compared with the products directly from zeolite upgrading. Thus, the process is more economically favorable.

    Abstract: A process for co-production of renewable diesel fuel range hydrocarbons and gasoline fuel range hydrocarbons from biomass-derived oils and fatty materials (e.g. triglycerides, diglycerides, monoglycerides, and free fatty acids) and biomass-derived polyol (e.g. sorbitol, xylitol, trehalose, sucrose, and sugar alcohol), respectively, in a same refinery hydrotreater with or without co-feeding of diesel fuel range hydrocarbons.

  • Patent number: 8137565
    Abstract: Methods and apparatus relate to handling of organic contaminants in aqueous streams. The methods and apparatus enable removing the contaminants, such as naphthenic acids, from the aqueous streams and then converting the contaminants into hydrocarbons. The removing and converting of the organic contaminates results in treated discharge and generation of the hydrocarbons, which add to amount of hydrocarbon recovery.

  • Publication number: 20120022305
    Abstract: 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.

  • Publication number: 20120017496
    Abstract: 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.

  • Publication number: 20120000820
    Abstract: 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.
