摘要： Residual oil from the processing of crude oil, natural bitumen or oil sand is mixed in a mixer with granular, hot coke as heat carrier (heat carrier coke) in a weight ratio of 1:3 to 1:30, where on the granules of the heat carrier coke there is first of all formed a liquid residue film which partly evaporates in the mixer. Gases and vapors and moist, sticky coke are withdrawn from the mixer. The mixture of coke and residual oil is introduced into a subsequently connected stirred tank in which the mixture slowly moves downwards while being stirred mechanically at a temperature of 450 to 600° C. and preferably at 480 to 550° C. Dry, flowable coke is withdrawn from the stirred tank. Usually, the dwell time of the heat carrier coke in the stirred tank is 1 to 30 minutes.

摘要： The present invention relates to a process of recovering monomeric esters of substituted or unsubstituted acrylic acid from polymer material having corresponding structural units by depolymerization by means of a fine-grained heat-transfer medium which is maintained above the depolymerization temperature of the polymer material. In a reactor, the polymer material is brought in contact with hot, mechanically fluidized heat-transfer medium. The resulting vapors are withdrawn and condensed, where the hot heat-transfer medium is continuously supplied at one end of the reactor, and cooled heat-transfer medium is discharged at the other end.

摘要： The aim of the invention is to improve an existing mixing device in such a manner that for a predetermined reactor length, retention time is increased and the material which is to be processed is transported at essentially the same speed irrespective of the radial distance thereof from the rotational axis. As a result, at least one row of blades is arranged on each shaft and each row of blades comprises at least two individual blades and the blades are fixed to the shaft at an incidence angle α in relation to the longitudinal axis of the shaft. The blades are curved in themselves, such that the blades form an angle of incidence α at the fixing point on the shaft and an angle of incidence β on the outer diameter DA. By virtue of the fact that a row of individual blades is used instead of a continuous screw, efficient mixing of charging material and coke can be achieved, the angle of incidence is reduced from the inside to the outside and the axial speed of the particles which are to be mixed is evened out on the total cross section of the reactor, thereby enabling a stop-type flow to be obtained.

摘要： High temperature flash distillation, for treating residual oils originating from crude oil refining, natural bitumen and/or tar sands, comprises feeding the oil to a mixer with granular hot coke, which serves as a thermal transfer medium. In mixing, 60-90% of the oil is vaporized. The non-vaporized fraction includes metal-containing asphaltenes. This fraction is further converted in the mixer, to oil vapor, gas and coke. Gases and vapor are withdrawn from the mixer, separately from the coke. The vapor phase is cooled and condensed to produce product oil. The gas itself is a further product. The coke is reheated and recycled to the mixer as the thermal transfer medium.
