I. Blyakhina et K. Urov, FORMATION OF DECOMPOSITION PRODUCTS FROM DICTYONEMA SHALE DURING THE LAST STAGES OF SEMICOKING, Gorucie slancy, 13(3), 1996, pp. 185-192
It has been established that maximum oil yield (on kerogen basis) is a
chieved at 430 degrees C for Dictyonema shale from Estonia. Further he
ating improves neither quantity nor quality of the oil obtained, but e
nergy requirements grow noticeably; therefore, it is not desirable to
process this shale at higher temperatures. As a result, prospects of c
o-processing kukersite and Dictyonema shale are not encouraging: the o
ptimum final temperature of heating is different for each of these sha
les.
