Abstract
A process and system for producing industrial-scale quantities of highly dispersed, thermally stable catalysts is disclosed. The process, which may be continuous production or batch production, includes mixing together the desired catalyst precursor materials, a combustible organic material and a solvent; evaporating the solvent, combusting the catalyst intermediate; and shaping final catalyst.
Claims20
A method of producing a catalyst, the method comprising:
- combining in a mixing vessel
- at least one decomposable precursor compound of a catalytically active metal or metal oxide,
- optionally, at least one decomposable precursor compound of a refractory metal oxide support,
- at least one combustible organic compound,
- optionally, a liquid mixing agent, such that a mixture is formed;
- in an evaporator, evaporating said liquid mixing agent, if present, and/or a portion of said combustible organic compound to produce a catalyst intermediate;
- in a furnace, heating said catalyst intermediate to the point of autoignition, and allowing said catalyst intermediate to combust, such that a combustion product is produced;
- optionally, calcining said combustion product;
- optionally, in a shaping unit, forming said combustion product into a predetermined shape;
- and
- optionally, in an activation unit, heating said combustion residue under activating conditions, to provide an activated catalyst.

An system for producing a catalyst, the apparatus comprising:
- means for mixing said predetermined amounts of said at least one precursor compound, said at least one combustible organic compound and said liquid mixing agent, if present;
- means for adding said predetermined amount of said at least one precursor compound, said at least one combustible organic compound and said liquid mixing agent, if present, to said mixing means;
- means for evaporating said liquid mixing agent, if present, and/or a portion of said combustible organic compound, to produce a catalyst intermediate;
- means for introducing said mixture into said evaporating means;
- means for heating said catalyst intermediate to the point of autoignition, such that a combustion product is produced;
- optionally, means for calcining said combustion product;
- optionally, means for shaping said catalyst;
- and
- optionally, means for activating said catalyst.
