For controlling the temperature in a hydrogenation system, should circulating hydrogen, circulating oil, or the inlet temperature be used? What factors need to be considered?
Either one can be used; recycled hydrogen is readily available, while recycled oil provides good cooling effects. The former is generally used.
Using recycled hydrogen should be quite energy-intensive, right?
On the far right side of the homepage, there is an option for one-on-one questions regarding hydrogen production; detailed answers can be found there
Theoretically, when the processing volume is fixed and the hydrogen-to-oil ratio is determined, the amount of circulating hydrogen remains constant. The reactor inlet temperature is primarily regulated by the reactor heater, while the temperature of the bed layer at the bottom of the reactor is controlled by the amount of cold hydrogen or cold oil present in the reactor.
