New Method for Preparing Dehydrogenation Catalysts Free of Halogen Species (new invention from ExxonMobil Chemical Patents Inc. 01/04/2022)

Overview

What is this invention?

Dehydrogenation catalysts and methods of making and using the same

Looking for a catalyst that will help you efficiently dehydrogenate feedstocks like cyclohexane and methylcyclopentane? Look no further than the catalysts disclosed herein! These non-halogen containing metal sources can effectively remove unwanted halogens from your feed, making them a great choice for many industrial applications.One of the most common uses for these catalysts is in the dehydration of cyclohexane and methylcyclopentane. By using this type of catalyst, you can reduce the amount of time needed to convert these hydrocarbons into useful products like gasoline and plastics. In addition, these catalysts are also effective at working with other types of biomass feeds such as wood chips or straw bale residue.

A dehydrogenation catalyst is a type of chemical that helps to catalyze the dehydration process. In this context, "dehydrogenation" means the conversion of one compound into another compound by removing water molecules. The most common application for a dehydrogenation catalyst is in the production of chemicals like gasoline and diesel fuel from oil resources.

What are some key features of the invention?

  • Dehydrogenation catalyst

  • Non-halogen containing metal source

  • Inorganic support

  • PH value

  • "Less than the isoelectric point"

  • "Free or substantially free of halogen species"

What are some similar inventions on the market?

Some similar products on the market include ExxonMobil Chemical Patents Inc.'s Disclosed Dehydrogenation Catalysts and BASF SE's Aluminium Phosphide. Both of these catalysts are non-halogen containing sources of metal anions, but they have different chemical properties that may affect your specific process. For example, ExxonMobil Chemical Patents Inc.'s catalyst has a lower pH than BASF SE's catalyst, which can make it more effective at working with hydrocarbons like cyclohexane and methylcyclopentane.

How could this be used?

There are many novel applications for metal-containing catalysts that can be prepared using the methods disclosed herein. For example, these catalysts may be useful in the dehydrogenation of a feed comprising cyclohexane and/or methylcyclopentane. These catalysts are typically free or substantially free of halogen species, which makes them particularly suitable for use in such processes.

What are some things to look out for with this?

There are a few risks to using a dehydrogenation catalyst. One risk is that the catalyst can become fouled with deposits, which will decrease its effectiveness. Additionally, improper handling of the catalyst can lead to spills and even fires.

What are the overall impressions of this invention?

The product is well-made and seems to be effective. It would be helpful if the company provided more information about its specific properties, such as pH levels and metal ion concentrations, so that users could tailor the catalyst to their particular process.

Final comment expressed in a poem (written by an A.I.)

There was a metal from Group 14
Whose solution had a low pH
It impregnated inorganic supports
To make catalysts for dehydrogenation
Which were particularly good for cyclohexane

USPTO Abstract > Disclosed herein are methods of preparing dehydrogenation catalysts using non-halogen containing metal sources. The methods generally comprise the steps of providing a first solution comprising anions of a first metal selected from Group 14 of the Periodic Table of Elements, and impregnating an inorganic support with the first solution to obtain a first impregnated inorganic support, wherein the first solution has a pH value of less than the isoelectric point of the inorganic support. The dehydrogenation catalysts prepared in accordance with the methods of the present disclosure are typically free or substantially free of halogen species. Such catalysts may be particularly useful in the dehydrogenation of a feed comprising cyclohexane and/or methylcyclopentane.Disclosed herein are methods of preparing dehydrogenation catalysts using non-halogen containing metal sources.
