Catalysts are primarily categorized into four types. They are (1) Homogeneous, (2) Heterogeneous (solid), (3) Heterogenized homogeneous catalyst and (4) Biocatalysts. 1) Homogeneous catalyst: In homogeneous catalysis, reaction mixture and catalyst both are present in the same phase.

Is a catalyst a reactant?

Thus, catalyst does not alter the equilibrium constant. (A catalyst can however change the equilibrium concentrations by reacting in a subsequent step. It is then consumed as the reaction proceeds, and thus it is also a reactant.
