摘要:
The invention relates to a hybrid nano sorbent that is capable of reducing and/or removing acidic gases in a gas stream. The hybrid nano sorbent includes at least (i) a nano-structured carbonous material including at least one organic functional group, (ii) at least one metal from at least one of groups 2A, 6B, 7B, 9B or 10B of the periodic table of elements, or (iii) a combination of (i) and (ii). The method for reducing and/or removing the acidic gases in a stream is also described.

摘要:
A method for producing olefins using a carbon nanotube catalyst is disclosed. Initially, a hydrocarbon feedstock is received. The hydrocarbon feedstock, the carbon nanotube catalyst, and steam are mixed in a thermal cracking reactor. The mixture is heated in the thermal cracking reactor to a particular temperature. The olefins are then separated from the mixture. The carbon nanotube catalyst can include carbon nanotubes coated with M1xOy and modified with M2mOn. M1 can be either the element silicon or tungsten, x can be an integer that represents the oxidation number of M1, and y can an integer that represents the number of oxygen atoms required by the oxidation number of M1. M2 can be a metallic element, m can be an integer that represents the oxidation number of M2, and n can be an integer that represents the number of oxygen atoms required by the oxidation number of M2.
