Abstract
The present invention provides a process for the production of hydrogen peroxide by direct catalytic reaction of hydrogen and oxygen that uses as a catalyst, a platinum group metal on an acidified support. The present invention also provides a sol-gel catalyst for use in the process and a process for the preparation of the catalyst.
Claims96
A process for the production of hydrogen peroxide by a direct combination of hydrogen and oxygen, the process comprising the steps:
- a. reacting a combination of hydrogen-containing gas stream and oxygen-containing gas stream on a catalyst in the presence of a solvent;
- b. maintaining (a) under low pressure;
- and
- c. conducting (a)-(b) in a microreactor system.
A sol-gel-produced catalyst comprising one or more platinum group metals and an acidified support.
A process for preparing a catalyst, the process comprising the steps of:
- a. preparing a gel of an acidified support by a sol-gel process that comprises the steps of:
- i. forming a sol comprising a precursor material of the support and a co-acid;
- ii. casting the sol into a mold to form a gel;
- iii. adding a platinum group metal at the gelation step of (ii);
- and
- iv. optionally, adding one or more additional platinum group metals;
- and
- b. drying the gel of (a);
- c. calcining the dried gel of (b);
- and
- d. reducing the calcined gel of (c).
A process for making hydrogen peroxide, comprising:
- flowing a process feed stream and a staged addition feed stream in contact with each other in a process microchannel to form a reactant mixture comprising O2 and H2, and contacting a catalyst with the reactant mixture in the process microchannel to convert the reactant mixture to a product comprising hydrogen peroxide;
- transferring heat from the process microchannel to a heat exchanger;
- and removing the product from the process micro channel.
