The disclosed invention relates to a method for restarting a synthesis gas conversion process which has stopped. The synthesis gas conversion process may be conducted in a conventional reactor or a microchannel reactor. The synthesis gas conversion process may comprise a process for converting synthesis gas to methane, methanol or dimethyl ether. The synthesis gas conversion process may be a Fischer-Tropsch process.

Synthesis gas conversion process

Method for stopping and restarting a Fischer-Tropsch process

This invention relates to a process for conducting a hydrocracking or a hydrotreating process in a microchannel reactor. This invention also relates to a process and apparatus for flowing a vapor and liquid into a plurality of microchannels in a microchannel processing unit.

Process and apparatus employing microchannel process technology

This invention relates to a process and an apparatus for conducting simultaneous endothermic and exothermic reactions in a microchannel reactor. A start-up procedure for the microchannel reactor is disclosed.

Process and apparatus for conducting simultaneous endothermic and exothermic reactions

Integrated Combustion Reactors (ICRs) and methods of making ICRs are described in which combustion chambers (or channels) are in direct thermal contact to reaction chambers for an endothermic reaction. Superior results were achieved for combustion chambers which contained a gap for free flow through the chamber. Particular reactor designs are also described. Processes of conducting reactions in integrated combustion reactors are described and results presented. Some of these processes are characterized by unexpected and superior results.

Integrated reactors, methods of making same, and methods of conducting simultaneous exothermic and endothermic reactions

Provided is a process and apparatus for exchanging heat energy between three or more streams in a millichannel apparatus, which millichannel apparatus may comprise a heat exchanger which may be integrated with a millichannel reactor to form an integrated millichannel processing unit. The combining of a plurality of integrated millichannel apparatus to provide the benefits of large-scale operation is enabled. In particular, the millichannel heat exchanger enables flexible heat transfer between multiple streams and total heat transfer rates of about 1 Watt or more per core unit volume expressed as W/cc.

Multi-stream multi-channel process and apparatus

Integrated Combustion Reactors (ICRs) and methods of making ICRs are described in which combustion chambers (or channels) are in direct thermal contact to reaction chambers for an endothermic reaction. Particular reactor designs are also described. Processes of conducting reactions in integrated combustion reactors are described and results presented. Some of these processes are characterized by unexpected and superior results, and/or results that can not be achieved with any prior art devices.

Integrated combustion reactor and methods of conducting simultaneous endothermic and exothermic reactions

The disclosed invention relates to a process, comprising: flowing a first reactant feed stream comprising a reactant substrate and a second reactant feed stream comprising an alkylating agent, an acylating agent or a mixture thereof, in a process microchannel in contact with each other to form a product comprising at least one alkylation product, at least one acylation product, or a mixture thereof; transferring heat from the process microchannel to a heat sink; and removing the product from the process microchannel.

Process using microchannel technology for conducting alkylation or acylation reaction

The invention provides apparatuses and techniques for controlling flow between a manifold and two or more connecting microchannels. Flow between plural connecting microchannels, that share a common manifold, can be made more uniform by the use of flow straighteners and distributors that equalize flow in connecting channels. Alternatively, flow can be made more uniform by sections of narrowed diameter within the channels. Methods of making apparatus and methods of conducting unit operations in connecting channels are also described.

Flow control through plural, parallel connection channels to/from a manifold

The disclosed technology relates to an apparatus, comprising: at least one microchannel, the microchannel comprising at least one heat transfer wall; a porous thermally conductive support in the microchannel in contact with the heat transfer wall; a catalyst or a sorption medium supported by the porous support; and a heat source and/or heat sink in thermal contact with the heat transfer wall.

Support for use in microchannel processing

Provided is a process and device for exchanging heat energy between three or more streams in a microchannel heat exchanger which can be integrated with a microchannel reactor to form an integrated microchannel processing unit. The combining of a plurality of integrated microchannel devices to provide the benefits of large-scale operation is enabled. In particular, the microchannel heat exchanger enables flexible heat transfer between multiple streams and total heat transfer rates of about 1 Watt or more per core unit volume expressed as W/cc.

Multi-stream microchannel device

An apparatus is described which comprises at least one process microchannel having a height, width and length, the height being up to about 10 mm, the process microchannel having a base wall extending in one direction along the width of the process microchannel and in another direction along the length of the process microchannel; at least one fin projecting into the process microchannel from the base wall and extending along at least part of the length of the process microchannel; and a catalyst or sorption medium supported by the fin.
