Abstract: A process for the hydrogenation of a liquid hydrocarbon-containing charge material, comprising the steps of: (i) supplying a high temperature high pressure liquid phase hydrogenation reactor with two separately and indirectly heated charge streams, (a) a primary charge stream comprising liquid hydrocarbon oils, oil residues, syncrudes, tars or pitches and optionally coal, and hydrogen-containing gas, and (b) a directly heated secondary gaseous charge stream comprising hydrogen-containing gas, and combining said indirectly heated primary charge stream and said indirectly and directly heated secondary charge stream prior to said liquid phase hydrogenation reactor, hydrogenating the combined streams to produce a hydrogenation product and separating the hydrogenation product in a hot separator to give a hot separator head product; wherein said indirectly heated primary and secondary charge streams are heated by separate heat exchange means by heat exchange with said hot separator head product, and said secondary charge stream, after heating by heat exchange, is directly heated with a hydrogenation gas heater.

Abstract: A method for pretreating a coal hydrogenation feedstock with preheated hydrogen containing a hydrogenation gas under high pressure and at elevated temperature, in a liquid phase slurry system, is disclosed. In this process a mixture of a slurry of finely ground coal and a slurry oil are fed to a preheater before being subjected to a hydrogenation and liquefaction reaction in a cascade of reactors at a pressure of from 100 to 40 bars and a temperature of 420.degree. to 490.degree. C. The reaction products are fed to a hot separator.In the process of the invention, prior to its preheating, a first partial stream of the hydrogenation gas, referred to as the slurry gas, is added to the mixture at process pressure. A second partial stream of the hydrogenation gas is heated by indirect heat exchange with a gaseous hot separator product in a gas heat exchanger. The mixture of slurry and slurry gas is preheated through indirect heat exchange in at least one heat exchanger downstream from the first gas heat exchanger, through which flows the hot separator head product after passing through the first heat exchanger. The heated second partial stream of hydrogenation gas is then added to the preheated mixture of slurry and slurry gas.This process provides improved heat transfer during the preheating of the coal-oil slurry and the mixture in a slurry with a hydrogenation gas.

Abstract: The invention concerns a process for recovering synthetic raw materials and fluid fuel components from used or waste plastics in accordance with patent application P 43 11 034,7. At least a partial flow of the depolymer produced according to this process is subjected, together with coal, to a coking process, fed to a thermal utilization system or introduced as a reducing agent into a blast furnace process. The depolymer can be used as an additive for bitumen and bituminous products.

Abstract: According to the process described, old or waste plastics are depolymerized into a pumpable phase and a volatile phase to allow recovery of chemical raw materials and liquid fuel components. The volatile phase is separated into a gaseous phase and a condensate. In order to simplify the process in comparison with the state of the art, the depolymerised product remaining after the volatile phase is separated is also heated together with the condensate or condensate fractions in the presence of hydrogen under pressure and is subjected to hydrotreating, after non-boiling components are removed, to produce syncrude.
