Publication number: 20230391617Abstract: Systems and methods are provided for conversion of methane and/or other hydrocarbons to hydrogen by pyrolysis while reducing or minimizing production of carbon oxides. The heating of the pyrolysis environment can be performed at least in part by using electrical heating within a first stage to heat the coke particles to a desired pyrolysis temperature. This electrical heating can be performed in a hydrogen-rich environment in order to reduce, minimize, or eliminate formation of coke on the surfaces of the electrical heater. The heated coke particles can then be transferred to a second stage for contact with a methane-containing feed, such as a natural gas feed. Depending on the configuration, pyrolysis of methane can potentially occur in both the first stage and second stage. In some aspects, the hydrogen-rich environment in the first stage is formed by passing the partially converted effluent from the second stage into the first stage.Type: ApplicationFiled: October 16, 2020Publication date: December 7, 2023Inventors: Ramesh GUPTA, Amrit JALAN, Hugo S.

Patent number: 11629056Abstract: Systems and methods are provided for production of carbon nanotubes and H2 using a reaction system configuration that is suitable for large scale production. In the reaction system, a substantial portion of the heat for the reaction can be provided by using a heated gas stream. Optionally, the heated gas stream can correspond to a heated H2 gas stream. By using a heated gas stream, when the catalyst precursors for the floating catalyst-chemical vapor deposition (FC-CVD) type catalyst are added to the gas stream, the gas stream can be at a temperature of 1000° C. or more. This can reduce or minimize loss of catalyst precursor material and/or deposition of coke on sidewalls of the reactor. Additionally, a downstream portion of the reactor can include a plurality of flow channels of reduced size that are passed through a heat exchanger environment, such as a shell and tube heat exchanger.Type: GrantFiled: December 16, 2020Date of Patent: April 18, 2023Assignee: EXXONMOBIL TECHNOLOGY AND ENGINEERING COMPANYInventors: Ramesh Gupta, Sumathy Raman, Amrit Jalan, Hugo S.

Patent number: 11563563Abstract: Embodiments afford secure transfer of security key type(s) between different database servers having different key hierarchies. For example, a key transfer may occur from a source server to a target server during a database migration process. Particular embodiments comprise a SQL transfer command statement (e.g., TRANSFER ENCRYPTION KEY) recognized by an engine. Syntax of the SQL transfer command includes a password and a filename for a security key. Upon receiving the SQL transfer command, the engine references an information repository to identify a relevant key hierarchy and key type, encrypts the security key with a key derived from password, and stores (exports) the encrypted security key in a file for consumption (import) at the target server. The SQL transfer command may further comprise a direction component determining flow of key information, and an override function to deal with error messages arising from any already-existing security key having the same name.Type: GrantFiled: November 7, 2019Date of Patent: January 24, 2023Assignee: SAP SEInventors: Rajnish Chitkara, Ramesh Gupta, Asif Iqbal Desai

Publication number: 20210331918Abstract: Systems and methods are provided for conversion of methane and/or other hydrocarbons to hydrogen by pyrolysis while reducing or minimizing production of carbon oxides. The conversion of hydrocarbons to hydrogen is performed in one or more pyrolysis or conversion reactors that contain a plurality of sequential fluidized beds. The fluidized beds are arranged so that the coke particles forming the fluidized bed move in a counter-current direction relative to the gas phase flow of feed (e.g., methane) and/or product (H2) in the fluidized beds. By using a plurality of sequential fluidized beds, the heat transfer and management benefits of fluidized beds can be realized while also at least partially achieving the improved reaction rates that are associated with a plug flow or moving bed reactor.Type: ApplicationFiled: April 21, 2021Publication date: October 28, 2021Inventors: Ramesh Gupta, Hugo S.
