摘要

Method for reducing deposition of cokes in heat-refining process of petroleum high-molecular hydrocarbons, characterized in that heat- treatment in a heating unit is effected in the presence of at least one compound (I) having at least one mercaprtoalkylthio group:P PHS--C. sub.m H.sub.2m --S--PPin which "m" is an integer of 2 to 4.

HS--C。 sub.m H.sub.m --S-

其中“ m”是2到4的整数。
