Title: Coal-mixed oil
Inventor: HIROYA OSAMU
IPC: C10L1/32
Filed: 1979-09-05
Abstract: PURPOSE: To obtain a coal-mixed oil which has excellent stability for a long period of time without causing sedimetation and coagulation, by dispersing pulverized coal into a hydrocarbon oil containing olefinic hydrocarbons.  
     CONSTITUTION: A petroleum fuel oil, e.g., crude oil, kerosene, or light oil, is mixed with 5vol% or more 8C or higher olefinic hydrocarbon of a boiling point of approx. 150°C or more, e.g., undecene or dodecene, preferably, and then the mixed hydrocarbon oil obtained is dispersed with pulverized coal of a grain size of approx. 50W100μ, for example, to obtain a coal-mixed oil. A crude oil obtained from the dry distillation of oil shale, light oil or heavy oil obtained from the fractionation of the crude oil, or oils obtained from the cracking of heavy oil may be used as the hydrocarbon oils as mentioned above because they contain olefinic hydrocarbons.
