The present invention provides a Fischer-Tropsch catalyst comprising greater than about 40% by weight of cobalt, and having a packed apparent bulk density greater than about 1.30 g/mL.

Fischer-tropsch catalyst

Spent catalyst () is removed from process microchannels () of a Fischer-Tropsch reactor by directing a jet of air () from an air knife () through slots of a protecting member (). The air knife is traversed across successive rows of process microchannels () in direction A. The spacer member () protects an internal microchannel architecture () of the process microchannels against damage by the air jet () which may approach or exceed sonic velocity as it is directed into the process microchannels.

Process and apparatus for removing solid catalyst

Catalyst

A catalyst is regenerated by an inventive process using a heat exchange fluid such as superheated steam to remove heat during the process relying on efficient heat transfer (e.g., enabled by the microchannel reactor construction) in comparison with prior art heat exchange relying on a phase change, e.g. between water and (partial or complete vaporization) steam, allows simplification of the protocols to enable transition at higher temperatures between steps which translates in reduced duration of the regeneration process and avoids potential water hammering risks.

Regeneration of catalyst

The present technology is directed to processes for conversion of synthesis gas in a tubular reactor to produce a synthetic product that utilizes high activity carbon monoxide hydrogenation catalysts and a heat transfer structure that surprisingly provides for higher per pass conversion with high selectivity for the desired synthetic product without thermal runaway.

Process for operating a highly productive tubular reactor

Catalyst compositions, methods of making catalysts, and methods of conducting Fischer-Tropsch (FT) reactions are described. It has been discovered that a combination of large crystallite size and high porosity results in catalysts and FT catalyst systems with high stability and low methane selectivity.
