Process for preparing a catalyst containing an active phase based on a group VIII metal and a porous support, comprising the following steps: bringing said support into contact with an organic compound comprising at least oxygen and/or nitrogen; bringing the porous support into contact with a solution containing a precursor of the active phase comprising a group VIII metal; drying the catalyst precursor at a temperature of less than 200 C. so as to obtain a dried catalyst precursor; calcining the dried catalyst precursor at a temperature of between 200 C. and 1100 C. under a stream of inert gas and/or of oxidizing gas, it being understood that the velocity of said gas stream, defined as the mass flow rate of said gas stream per volume of catalyst per hour, is greater than 1 litre per gram of catalyst and per hour.

A cobalt catalyst precursor is described comprising cobalt oxide crystallites disposed within pores of a titania support, wherein the cobalt oxide crystallites have an average size as determined by XRD in the range 6 to 18 nm, and the titania support is a spherical titania support with a particle size in the range 100 to 1000 m, wherein the catalyst precursor has a pore volume of 0.2 to 0.6 cm.sup.3/g and an average pore diameter in the range 30 to 60 nm, and wherein the catalyst precursor has a ratio of the average cobalt oxide crystallite size to the average pore diameter in the range 0.1:1 to 0.6:1. The catalyst precursor may be reduced to provide catalysts suitable for use in Fisher-Tropsch reactions.

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.

The invention relates to a molecular sieve composition, a process of preparing same and use thereof in the production of lower olefins. The molecular sieve composition comprises an aluminophosphate molecular sieve and a CO adsorbing component, both of which are present independently of each other. When the molecular sieve composition is used as a catalyst for producing lower olefins using synthesis gas as a raw material, the molecular sieve composition has the advantages of high selectivity to lower olefins and the like.

A unique process and catalyst is described that operates efficiently for the direct production of a high cetane diesel type fuel or diesel type blending stock from stochiometric mixtures of hydrogen and carbon monoxide. This invention allows for, but is not limited to, the economical and efficient production high quality diesel type fuels from small or distributed fuel production plants that have an annual production capacity of less than 10,000 barrels of product per day, by eliminating traditional wax upgrading processes. This catalytic process is ideal for distributed diesel fuel production plants such as gas to liquids production and other applications that require optimized economics based on supporting distributed feedstock resources.
