    摘要： A liquid hydrocarbon such as a natural gas liquid generally contains a small amount of mercury in a state of elemental mercury, ionized mercury, ionizable mercury compounds, which are requested to be removed thoroughly. Further, organic mercury compounds are contained in some natural gas liquid and other liquid hydrocarbons depending on their district of production, and its removal is also necessary.Already known adsorbents can adsorb elemental mercury and organic mercury compounds in a liquid hydrocarbon, but they hardly adsorb ionizable mercury compounds and ionized mercury derived from the ionizable mercury compounds.According to the preesent invention which comprises contacting the liquid hydrocarbon with a sulfur compound represented by a general formula MM'S.sub.x, wherein M is selected from a group consisting of alkali metal and ammonium radical, M' is selected from a group consisting of alkali metal, ammonium radical and hydrogen an x is a number of at least 1, the sulfur compound and mercury in the liquid hydrocarbon reacts to form mercury sulfide which is insoluble in the liquid hydrocarbon to be separated therefrom.If the liquid hydrocarbon contains organic mercury compounds together with elemental mercury ionized mercury and ionizable mercury compounds, the above-mentioned process is to be combined with a process of contacting the liquid hydrocarbon with an adsorbent comprising heavy metal sulfide to adsorb the organic mercury compounds together with the mercury sulfide which is formed in the above-mentioned process.

    摘要： An improved method for recovering hydrocarbon and other values from shale oil rock, whereby shale oil rock, during the reaction with a reagent and steam, is shattered to the extent that the hydrocarbon values and the unwanted pulverized gangue is collected such as via cyclones or a dust collector; the desired hydrocarbon values as volatile products may be recovered or further reacted in a separate reactor; a series of cyclones may be used to separate the dust from the hydrocarbon values; recoveries of over 90% of the hydrocarbon values and higher are achieved; as a further advantage, the collected dust may be used as an intermediate for making cement.

    摘要： An improved process for removing metals from heavy oils and other hydrocarbon feed streams is disclosed. The process includes adding phosphorus sulfide to the hydrocarbon feed stream under suitable demetallizing conditions. It is believed that phosphorus sulfide reacts with the metals contained in the hydrocarbon containing feed stream to form oil insoluble compounds that can be removed from the hydrocarbon containing feed stream by any conventional method, such as filtration, centrifugation, or decantation.
