摘要:
The conversion of diols to mono-alcohols as fuel blendstocks. In one embodiment hydrotreating processes are described that selectively convert glycols to mono-alcohols that can be blended as biofuels. Both NiMo and CoMo catalysts are active for the reaction and reaction conditions can also impact the selectivity of mono-alcohols.
摘要:
This invention is a method for converting biomass derived pyrolysis oil (bio-oil) into materials that will be more useful for transportation fuels including the following two steps: 1) solubilizing and extracting bio-oil oxygenates, and 2) zeolite catalyzed hydrogenation of the oxygenates into renewable fuel range materials.
摘要:
Cellulose and hemicellulose from biomass can be broken down to C6 and C5 sugars and further converted to corresponding sugar alcohols. It is now found that a new catalyst, MoS2, is active for the hydrogenation of sugar alcohols to hydrocarbons. Combining the technologies listed above allows us to convert the cellulose/hemicellulose to liquid hydrocarbons.
摘要:
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.
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.
摘要:
A composition, containing vanadium and a support, wherein at least a portion of the vanadium has crystallite sizes of less than about 100 Å as determined by an analytical method such as X-Ray Diffraction, 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 mercury adsorption stage.
摘要:
An integrated process for the conversion of carbohydrate containing materials to gasoline boiling range hydrocarbons is disclosed. A carbohydrate containing material may be converted to a hydrogenated carbohydrate containing material with a bi-functional catalyst. The hydrogenated carbohydrate containing material may be reacted in the presence of another catalyst to form a reaction product containing non-aromatic and aromatic gasoline boiling range hydrocarbons.
摘要:
A method and apparatus for removing sulfur from a hydrocarbon-containing fluid stream wherein desulfurization is enhanced by improving the contacting of the hydrocarbon-containing fluid stream and sulfur-sorbing solid particulates in a fluidized bed reactor.
摘要:
Methods for producing C10-C30 hydrocarbons from fatty compounds are provided in which at least a portion of the hydrogen required to accomplish the conversion is generated from by-products of the conversion process. Light hydrocarbons, especially propane, produced during the conversion of triglyceride compounds are used to generate hydrogen which is used in the conversion process thereby reducing the need for outside hydrogen sources.
