A regenerable sorbent for the removal of acid gas from a fluid stream. The regenerable sorbent is made from raw materials such as iron mineral, expansive clay and starch. Acid gas is removed from the fluid stream by a process where the raw materials are obtained, crushed, sifted, possibly pelletized, calcined and contacted with the fluid stream containing the acid gas.

Use of iron ore agglomerates for acid gas removal

A process for upgrading a heavy hydrocarbon feed includes the steps of: providing a hydrocarbon feedstock including a fraction having a boiling point greater than or equal to about 320.degree. C.; mixing the feedstock with steam so as to provide a reaction feedstock; providing a catalyst including a first metal selected from the group consisting of Group VIII non-noble metals and a second metal selected from the group consisting of alkali metals, the first and second metals being supported on a support selected from the group consisting of kaolin, alumina, silica, carbon, petroleum cokes and mixtures thereof; and contacting the reaction feedstock with the catalyst at steam conversion conditions so as to provide a reaction product including an upgraded hydrocarbon fraction.

A natural active stable catalyst for use in the hydrodemetallization (HDM) and the hydroconversion (HC) of heavy crudes and residues and, in particular, a method for the preparation of the catalyst from natural clay and a process for the treatment of heavy crudes and residues with the catalyst. The catalyst is free of hydrogenating metals of Groups VIB and VIII of the Periodic Table and comprises primarily iron, silica and alumina derived from the composition of the natural clay. The catalyst possesses a surface area of between 20 to 100 m.sup.2 /g, a total pore volume of between 0.20 to 0.90 cc/g, where 50 to 100% of the total pore volume contains pores of diameter greater than 400 .ANG.. The catalyst has a ratio I(Fe)/I(Si+Al) of between 0.2 to 0.9 as determined by XPS.
