摘要:
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.

There is provided a process for converting high free fatty acid containing feedstock such as acidulated soapstock into hydrocarbon compound especially fuel range hydrocarbons using amidation as a pretreatment step followed by hydroprocessing.
摘要:
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.

摘要:
Conversion of renewable hydrocarbons to transportation fuels is required to reduce carbon emission, limit the use of fossil fuels, and develop renewable energy sources. Sorbitol, xylitol and trehelose are polyalcohols generated from the liquefaction of various sugars and carbohydrates in biomass from algae, corn, sugarcane, switchgrasses, and biological wastes. Mixtures of aqueous polyols and fuel feedstocks are catalyzed over metal catalysts to produce hexanes, pentanes, and lighter hydrocarbons. By managing the catalyst, reaction conditions and sulfur content, the octane value of the product fuel is dramatically increased.
摘要:
A catalyst composition and a process of using a catalyst composition for preparing high molecular weight hydrocarbons, such as polymethylene, from a fluid containing hydrogen and carbon monoxide are disclosed. The catalyst composition contains ruthenium and a treated silica support component. The treated silica support component is prepared by a process including contacting a silica support component, such as silicon dioxide, and a treating agent, such as a silicon-containing compound.
摘要:
A composition, containing vanadium, potassium and a support is disclosed. A method of preparing such composition is also disclosed. The composition is employed in a process to remove a heavy metal from a gaseous feed stream which can optionally include a separate heavy metal adsorption stage.
摘要:
Methods for producing C10-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 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.
