  • Patent number: 12709713
    Abstract: The present application provides a treatment method and device for a waste plastic. A first aspect of the present application provides a treatment method for a waste plastic, including: firstly subjecting the waste plastic to a first pre-treatment to remove impurity and grease on a surface of the waste plastic, then subjecting the waste plastics to a second pre-treatment to convert a solid waste plastic into one in flow state; and finally, subjecting the waste plastic in flow state to a first cracking treatment and a second cracking treatment in sequence. Through the method provided in the present application, while cracking the waste plastic, chlorine element in the waste plastic may be removed by a multi-stage adsorption, which reduces chlorine content in the cracked oil, reduces pressure and burden in subsequent refining, and meets the limitation of the chlorine content in cracked products in downstream processes.

  • Publication number: 20260186973
    Abstract: Methods, systems, and devices for increased file loads using file based optimization (FBO) and prefetch within a memory system are described. A system may support using a prefetch command to prioritize prefetching for artificial intelligence (AI) related data (or other high priority data). A host system may transmit a prefetch command for the AI-related data before performing one or more AI operations that use the data. In response, the memory system may prefetch the AI-related data and store the data in a cache. The storage of the AI-related data in the cache may be prioritized over other data types associated with lower priorities. The host system may transmit an FBO command to defragment the AI-related data in the memory system prior to the prefetch, which may reduce latency of the prefetch.

  • Publication number: 20260178230
    Abstract: Methods, systems, and devices for techniques for a sequential write protection mode in a memory system are described. A memory system may receive one or more commands to write data to associated sequential memory addresses using a write automation block (WAB) while monitoring the addresses of the data. In the case that a write command may be associated with a non-sequential memory address, the memory system may store an associated pointer to a cache. The memory system may continue to write data indicated via incoming commands using the WAB until the memory system detects and writes the sequential command or a threshold quantity of commands have been received. If the threshold is reached prior to receiving the missing command, the memory system may disable the WAB and transmit an error message. The memory system may block and return error messages to any subsequent commands until the missing command is received.
