Patent ID: 7588734

Claim:
A laboratory reactor for the kinetic study of catalytic reactions calling for a gaseous reaction phase and a liquid reaction phase, said reactor comprising: a tubular reactor having a capillary shape with an internal diameter (Dr), a fixed bed of catalyst grains wherein said fixed bed is in the form of a uniform arrangement of the catalyst grains within the reactor, every cross-sectional unit of the reactor comprising a defined and constant number of catalyst grains, and said number of catalyst grains being 1, 2, 3, or 4, said grains having a diameter (Dg) of that of an essentially spherical shape or an essentially cylindrical shape, or an equivalent diameter (De) of a shape having a surface to volume ratio of essentially that of a sphere and wherein the ratio of Dr to De is dependent on the grain number per cross sectional unit and wherein: where the grain number is 1, the ratio of Dr to De is between 1.1 and 2, where the grain number is 2, the ratio of Dr to De is between 2.1 and 2.3, where the grain number is 3, the ratio of Dr to De is between 2.3 and 2.5, where the grain number is 4, the ratio of Dr to De is between 2.5 and 2.7.
