The dry process is much more thermally efficient than the wet process. Firstly, and most obviously, this is because the meal is a dry powder and there is little or no water that has to be evaporated. Secondly, and less obviously, the process of transferring heat is much more efficient in a dry process kiln

Pour this mixture (in which the alum is not very soluble) over the crystals in the funnel and again let the liquid drain. Finally, wash the crystals with 10 mL of ethanol. Leave the vacuum on for about 5 minutes in order to draw air through the crystals to dry them. Carefully scrape the crystals off the filter paper and onto a watch glass

1.5.4 Water–gas shift reaction. The water–gas shift reaction (WGSR) process is an intrinsic inclusion into the reforming process; WGS is seen to increase the H 2 /CO ratio. Most catalysts in the steam reforming of ethanol produce CO. WGSR is the reaction of an equimolar mixture of steam and carbon monoxide and the process is moderately
