Abstract: In a method of video encoding, whether an adaptive color transform (ACT) is to be applied to a current block is determined. The current block includes color components, the color components including a luma component, a first chroma component, and a second chroma component. Based on the ACT being determined to be applied to the current block, a color space conversion is applied on the current block based on color space conversion equations to generate modified color components of the current block. The current block is encoded based on the modified color components of the current block.

Abstract: The process converts ethylene in a dilute ethylene (dry gas) stream that may be derived from an FCC product to propylene. The process includes an oligomerization step to convert ethylene in the dilute ethylene stream to heavier olefins, and a second reaction step to convert the heavier olefins to propylene.
