Conversion process for soild, hydrocarbonaceous materials

Abstract From the Canadian patent

A process for converting solid hydrocarbonaceous, materials, such as coal to liquid and gaseous products, comprising: (1) preparing a slurry from slurry oil a, hydrogenation catayst and the hydrocarbonaceous material; (2) hydrogenating the hydrocarbonaceous material to liquid and gaseous hydrogenation products, the liquid hydrogenation product containing suspended particles of ash and catalyst; (3) gravitationally separating the liquid hydrogenation product into a first stream and a second stream the first, stream having both a lower ash concentration than the liquid hydrogenation product and a greater catalyst:ash ratio than the second stream; (4) recycling at least a portion of the first …
