Sugar Seed Slurry Requirement Calculation for B and C ,Coal liquefaction catalyst development Quarterly progress

The basic requirements of organic solvents to be used for sugar seed slurry preparation are as follow Boiling point of organic solvent be lower than waterSo that after introduction of slurry in pans all organic solvent gets evaporated and crystal get spread well Solubility of sucrose in such organic solvent should be minimum or negligibleAfter considerable experimentation, use of the charging device was abandoned because of problems with plugging, temperature upsets, and catalyst coking The effort in Catalyst Aging Tests with Eastern and Western Coal was centered around preparation of enough liquefaction solvent for the DOE program.
