Dehydrogenation of liquid fuel in microchannel catalytic reactor
First Claim
1. In a process for the delivery of hydrogen from an organic compound capable of reversible hydrogenation/dehydrogenation wherein the organic compound is initially in its hydrogenated form and subsequently catalytically dehydrogenated under dehydrogenation conditions in a reactor forming hydrogen and byproduct dehydrogenated organic compound, the improvement in the dehydrogenation step which comprises:
- (a) introducing said organic compound capable of reversible hydrogenation/dehydrogenation in liquid form to a microchannel reactor incorporating a dehydrogenation catalyst;
(b) effecting dehydrogenation of said organic compound under liquid phase conditions whereby said organic compound and said byproduct dehydrogenated organic compound remain in the liquid phase;
(c) recovering a reaction product comprised of a byproduct dehydrogenated organic compound and gaseous hydrogen;
(d) separating the reaction product comprised of said liquid phase dehydrogenated organic compound and gaseous hydrogen into a gaseous hydrogen fraction and liquid phase byproduct dehydrogenated organic compound;
(e) recovering the gaseous hydrogen; and
, (f) recovering the liquid byproduct dehydrogenated organic compound.

Abstract
The present invention is an improved process for the storage and delivery of hydrogen by the reversible hydrogenation/dehydrogenation of an organic compound wherein the organic compound is initially in its hydrogenated state. The improvement in the route to generating hydrogen is in the dehydrogenation step and recovery of the dehydrogenated organic compound resides in the following steps: introducing a hydrogenated organic compound to a microchannel reactor incorporating a dehydrogenation catalyst; effecting dehydrogenation of said hydrogenated organic compound under conditions whereby said hydrogenated organic compound is present as a liquid phase; generating a reaction product comprised of a liquid phase dehydrogenated organic compound and gaseous hydrogen; separating the liquid phase dehydrogenated organic compound from gaseous hydrogen; and, recovering the hydrogen and liquid phase dehydrogenated organic compound.
