摘要： The present invention relates to a process for the separation of components or mixtures from feedstreams using magnetically stabilized beds. More particularly, the invention relates to the removal of contaminants from fluid streams in a continuous process by use of solid absorbents which also include a magnetizable component capable of adsorbing the contaminants from the fluid streams wherein the adsorption and desorption are carried out at substantially the same pressure. The adsorbent particles and magnetizable component which flow or move through the vessel are stabilized against fluid by-passing and solids back-mixing and recirculation generally associated with fluidized beds (except for the flow or movement of the solids through the contacting vessels) during adsorption and desorption by the use of an applied magnetic field. The use of the applied magnetic field enables one to use small size adsorbent particles without encountering high pressure drops as with fixed bed processes. The small adsorbent particles give faster transfer of the contaminants than with larger particles which allows for closer approach to equilibrium, the use of smaller beds than by use of fixed beds and the possibility of using one bed rather than a multiplicity of beds as with fixed bed processes.
摘要翻译：本发明涉及使用磁稳定床从成分流分离成分或混合物的方法。更具体地，本发明涉及通过使用固体吸收剂在连续方法中从流体流中除去污染物，固体吸收剂还包括能够吸附来自流体物流的污染物的可磁化成分，其中吸附和解吸基本上相同压力。流动或移动通过容器的吸附剂颗粒和可磁化组分是稳定的，以防止在吸附期间通常与流化床（固体通过接触容器的流动或移动除外）相关的流体旁路和固体回混和再循环，通过使用施加的磁场解吸。使用所施加的磁场使得能够使用小尺寸吸附剂颗粒，而不会像固定床方法一样遇到高压降。小的吸附剂颗粒比使用更大的颗粒更容易接近平衡，使用比使用固定床的更小的床和使用一个床而不是多个床的可能性与固定床相比更容易传递污染物过程。

摘要： A delayed coking process is provided in which the fresh oil is introduced into the coker product fractionator and in which a stream of heavy oil product is withdrawn from the fractionator before it can contact the fresh oil. The stream of heavy oil product withdrawn from the fractionator is subjected to solvent separation to produce a high Conradson carbon product and a low Conradson carbon product. At least a portion of the low Conradson carbon product is recovered and the high Conradson carbon product is recycled to the coking zone.

摘要： A novel composition is formed by suspending a carbonaceous adsorbent in a branched hydrocarbon solvent. In addition, said powdered carbonaceous adsorbent suspended in a hydrocarbon solvent, preferably a branched hydrocarbon solvent, is an effective adsorbent-extractant for removing both soluble and insoluble organic materials from waste water. Use of this suspension as an adsorbent enables the use of a continuous adsorption process having high capacity for removal of contaminants, fast contaminant removal rates and high adsorbent utilization while permitting easy staged contacting. The spent suspension may then be regenerated by vapor stripping or solvent extraction.
