摘要： The present invention is a process to remove a major portion of metals and coke precursors from a hydrocarbon stream. The steps of the process include contacting the feedstream with a hydrocarbon insoluble adsorbent, recovering the oil which does not adsorb and removing the metals and coke precursors from the adsorbent.

摘要： The present invention provides for a method of decreasing the metals content of metal containing petroleum streams by forming a mixture of the petroleum fraction containing those metals and an essentially aqueous electrolysis medium, and passing an electric current through the mixture at a voltage, pH and time sufficient to remove the metals such as Ni, V and Fe from the stream (i.e. to produce a petroleum fraction having decreased content of the metals). The cathodic voltage is from 0 V to -3.0 V vs. SCE at a pH of from 6 to 14, preferably 7 to 14, most preferably above 7 to 14.The invention provides a method for enhancing the value of petroleum feeds that traditionally have limited use in refineries due to their Ni and V content.

摘要： The present invention is predicated on the discovery that the addition of certain free radical initiators to thermal conversion processes results in increased thermal conversion rate at a given temperature without any substantial increase in the amounts of gaseous products formed. This permits operating the thermal conversion process at lower temperatures than otherwise practical. Indeed, the present invention is especially useful in thermal cracking processes like fluid coking. In this embodiment, a free radical initiator is added, without the addition of a hydrogen donor diluent, to a feedstock which is thermally cracked in a fluidized bed of particulate solids and at lower temperatures than otherwise employed, thereby increased amounts of liquid products are obtained.

摘要翻译： 本发明的前提是基于以下发现：将热自由基引发剂加入到热转化过程中导致在给定温度下的热转化率增加，而形成的气体产物的量没有任何显着增加。 这允许在比实际更低的温度下操作热转换过程。 实际上，本发明特别适用于热裂解过程如流体焦化。 在该实施方案中，将自由基引发剂加入到不添加氢供体稀释剂的情况下，在颗粒固体的流化床中和在比其它方式更低的温度下热裂化的原料中，由此获得增加量的液体产物 。

摘要： Disclosed is a method for enhancing the removal of nitrogen, sulfur, or both from oil-shale. The oil-shale is treated with either (i) steam at a temperature from about 250.degree. C. to about 350.degree. C. to remove nitrogen; or (ii) water at a temperature from about 200.degree. C. to about 350.degree. C. to remove both nitrogen and sulfur.
