you would like to synthesize sorbitol (c6h14o6) from glucose and h2 to develop a sugar-free caramel syrup. a feed containing a glucose-water slurry is mixed with a stream of fresh h2 and an h2 recycle stream, for a total of 20% excess h2. the weight ratio of water to glucose is 1:10. the combined slurry and gas stream is sent to a reactor, where 70% of the glucose is converted to sorbitol (reaction 1).
