Abstract: A process for producing light olefins comprising thermal cracking. Hydrocracked streams are thermally cracked in a steam cracker to produce light olefins. A pyrolysis gas stream is separated into a light stream and a heavy stream. A light stream is separated into an aromatic naphtha stream and a non-aromatic naphtha stream. The aromatics can be saturated and thermally cracked. The integrated process may be employed to obtain olefin products of high value from a crude stream.

Abstract: A lubricant for a copper alloy die-casting die is mainly prepared by an inorganic nano-powder, an organic substrate material, and an organic resin material. In the present disclosure, the use of oil-based lubricants as a basis and the reduction of the content of oil in the lubricant yield improved oil selection and proportion, which cooperates with the corresponding higher proportion of inorganic powder material mixture and a more suitable spraying amount applied on the surface of the die to exert a good lubricating effect on products with complex and irregular shapes in the inner cavity of a die-casting die. At the same time, the production cost of the lubricant is low. Copper alloy die castings produced after a lubrication process have a high yield rate and smooth surfaces without casting defects.

Abstract: Systems and methods are provided for performing hydrodeoxygenation of bio-derived feeds while maintaining the hydrodeoxygenation catalyst in a sulfided state. During hydrodeoxygenation, a hydrogen-containing stream is provided to the hydrodeoxygenation reactor as a hydrogen treat gas to provide hydrogen for the reaction. In some aspects, the hydrogen treat gas used for hydrodeoxygenation can be formed at least in part from hydrogen that has been used as a stripping gas for removing H2S from a rich amine stream. In other aspects, H2S can be stripped using water vapor, and a resulting overhead HS stream can be compressed prior to incorporation of the H2S into a hydrogen-containing stream. The resulting hydrogen-containing stream can include sufficient H2S to substantially maintain the catalyst in the hydrodeoxygenation stage in a sulfided state.
