摘要： A process utilizing a sorbent in a manner which provides a greater and more efficient utilization of the sorbent for the removal of sulfur, or sulfur-containing compounds, from a process streamwherein a sulfur-containing process stream is passed through a fixed-bed of sorbent from one side of the bed to the opposite side, sulfur removed, and passage of the sulfur-containing process stream through said fixed-bed of sorbent continued to breakthrough of sulfur from the exit side of the bed. Then the direction of flow of the sulfur-containing process stream is reversed without desorption of the sulfur from the sorbent, and passage of the sulfur-containing process stream in said reverse direction through the bed again continued until breakthrough of sulfur from the side of the sorbent bed opposite the former entry side. In a preferred embodiment, two or more of the fixed-beds of sorbent are staged, or placed in series.

摘要： A hydroprocessing process includes a cocurrent flow liquid reaction stage, a countercurrent flow liquid reaction stage and a vapor reaction stage in which feed components are catalytically hydroprocessed by reacting with hydrogen. Both liquid stages both produce a liquid and a vapor effluent, with the cocurrent stage liquid effluent the feed for the countercurrent stage and the countercurrent stage liquid effluent the hydroprocessed product liquid. Both liquid stage vapor effluents are combined and catalytically reacted with hydrogen in a vapor reaction stage, to form a hydroprocessed vapor. This vapor is cooled to condense and recover a portion of the hydroprocessed hydrocarbonaceous vapor components as additional product liquid. The uncondensed vapor is rich in hydrogen and is cleaned up if necessary, to remove contaminants, and then recycled back into the cocurrent stage as hydrogen-containing treat gas. Fresh hydrogen is introduced into the countercurrent stage and the countercurrent stage effluent contains sufficient, and preferably all of the hydrogen for the vapor stage reaction.

摘要： An improved wax isomerization catalyst is described which is a hydrogenation metal on halogenated refractory metal oxide support catalyst characterized in that the catalyst is prepared by depositing the hydrogenation metal on the refractory metal oxide support followed by fluoriding using a low pH fluorine source such as aqueous HF. Thereafter the catalyst is crushed to expose inner surfaces, the crushed catalyst being sieved to remove fines, the catalyst charge having an average particle diameter of 1/32 inch and smaller across the longest continuous cross sectional dimension, preferably between 1/64 to 1/32". Alternatively, the catalyst is made by depositing a hydrogenation metal on a refractory metal support, crushing the material to a particle size of 1/32 inch and smaller across the longest continuous cross-sectional dimension and fluoriding said material using acidic fluorine source such as HF. Following sizing the sized catalyst is activated by heating in a hydrogen atmosphere.Isomerization using this "sized" catalyst is marked by the production of an isomerized dewaxed oil product having unexpectedly high VI and superior levels of selective conversion of wax to liquid isomerized product.
