Probably someone forgot to write /C in the first case.

My objective is how to reduce the loss of catalyst after 20 cycle of hydrogenation process.

The reaction is usually filtered over Celite and that is how the solid Pd/C is removed from the reaction mixture.

Hi – Pd(OH)2 (Pearlman’s catalyst) is generally pretty active. To directly compare Pd vs Pt hydrogenation catalysts I would suggest going to Encyclopedia of Reagent for Organic Synthesis (the electronic version). If you don’t have that, then there is a version available on the Internet Archive you can view for free:

Is one (hydroxide) more likely to cause dechlorination than the other?

It can, but reduction of ketones requires significantly higher pressures.

Do you mean a C-Cl bond in the molecule you are planning to hydrogenate? Or if you are adding NaCl or some other chloride salt?
