Two routes were used to rejuvenate spent residue hydroprocessing catalysts by leaching foulant metals. In the first, deoiled spent catalyst containing coke and deposited metals in sulfide form was chemically treated to remove the metal foulanta. In the second, deoiled spent catalyst was decoked by c
## Abstract A number of volatile pyrolyzates of largeβscale thermolysis of ABS and SAN plastics, which include phenyl substituted aliphatic nitriles and dinitriles, have been tentatively identified by GCβMS. The exact isomers of most of these compounds have, however, not been specified, owing to li
