Abstract
Catalysts and processes for producing catalysts for neopentane production are provided herein. A process includes reducing a catalyst precursor comprising a transition metal and an inorganic support at a temperature less than 500° C. to produce a catalyst. Also provided herein are processes to produce neopentane using the catalysts described herein and neopentane compositions produced therefrom.
Claims24
A process for making a demethylation catalyst, the process comprising reducing a catalyst precursor comprising a transition metal and an inorganic support at a temperature less than 500° C. to produce the demethylation catalyst, wherein the catalyst precursor is reduced in the presence of at least 100 standard cubic centimeters per minute of hydrogen.
A process for producing neopentane, the process comprising:
- (a) reducing a catalyst precursor comprising a transition metal and an inorganic support at a temperature less than 500° C. to produce a demethylation catalyst;
- and
- (b) contacting a stream including a C6-C8 alkane with hydrogen in the presence of the demethylation catalyst to produce a demethylation product including at least 10 wt % neopentane based on the weight of the demethylation product,
- wherein the demethylation catalyst exhibits a conversion rate of the C6-C8 alkane of at least 60%.
A process for producing neopentane, the process comprising:
- (a) reducing a catalyst precursor comprising a transition metal and an inorganic support at a temperature less than 500° C. to produce a demethylation catalyst;
- and
- (b) contacting a stream including a C6-C8 alkane with hydrogen in the presence of the demethylation catalyst to produce a demethylation product including at least 10 wt % neopentane based on the weight of the demethylation product,
- wherein the demethylation product comprises 25 wt % to 50 wt % neopentane based on the weight of the demethylation product and zero wt % to 10 wt % C6+ hydrocarbon components based on the weight of the demethylation product.
