Propylene polyol conversion to olefin monomer

A process comprising:

• a) adding a feed stream comprising one or more propylene polyols, hydrogen, and optionally water, to a catalytic conversion reaction zone in the presence of a first solid acid catalyst component and a hydrogenation catalyst component to form a first reaction mixture;
• b) reacting the first reaction mixture at a temperature in the range of from 20° C. to 600° C., a pressure in the range of from 100 psig (689 kPag) to 1,500 psig (10,340 kPag), or a combination thereof, to form a catalytic conversion product stream comprising a propanol component;
• and
• c) adding the catalytic conversion product to a first distillation column to produce a catalytic conversion product overhead stream and a catalytic conversion product bottoms stream and withdrawing the catalytic conversion overhead product stream as a first conversion product.
