an API gravity from about 10 to about 21; a density @ 15??? C. from about 0.93 to about 1.0; greatly reduce metals content, including V and Ni; a greatly reduced viscosity of more than 20 fold lower than the feedstock (for example as determined at 40??? C.), and yields of liquid product of at least 60 vol %, preferably the yields are greater than about 75 vol %.
