摘要:
A sorbent composition comprising a vanadium compound and a ZrO2 support material is disclosed. Methods of making and using the composition to remove heavy metals or heavy metal containing compounds from a fluid stream are also provided. Such methods are particularly useful in the removal of mercury and mercury compounds from flue gas streams produced from the combustion of hydrocarbon-containing materials such as coal and petroleum fuels.

摘要:
Processes for the conversion of hydrocarbons boiling in the temperature range of from about 80° F. to about 1000° F. to diesel boiling range hydrocarbons, and processes for increasing the cetane number and amount of n-C17 hydrocarbon products in such processes. Diesel boiling range hydrocarbons may be produced by contacting a hydrocarbon boiling in the above-mentioned boiling range with a triglyceride-containing compound to form a mixture, and then contacting the mixture with a hydrotreating catalyst under suitable reaction conditions.
