A method for interconversion between protocols, including the following steps: pre-establishing a publication/subscription list; when a packet published by a publisher is received, searching the publication/subscription list for a protocol type of the packet; extracting a packet data payload from the packet; determining whether a size of the packet data payload is less than a preset combination threshold; if yes, sending the packet data payload to a packet data payload queue of the publisher, and combining a packet data payload in the packet data payload queue when a size of the packet data payload queue reaches a preset transmission threshold or no new packet is received after a preset waiting duration; searching the publication/subscription list for all subscribers corresponding to the publisher; and performing protocol conversion on the packet one by one based on protocol types used by the corresponding subscribers, and sending protocol-converted packets to the corresponding subscribers.

Method for interconversion between protocols

A molecular sieve has a silica/alumina molar ratio of 100-300, and has a mesopore structure. One closed hysteresis loop appears in the range of P/P=0.4-0.99 in the low temperature nitrogen gas adsorption-desorption curve, and the starting location of the closed hysteresis loop is in the range of P/P=0.4-0.7. The catalyst formed from the molecular sieve as a solid acid not only has a good capacity of isomerization to reduce the freezing point, but also can produce a high yield of the product with a lower pour point. The process for preparing the catalyst involves steps including crystallization, filtration, calcination, and hydrothermal treatment.
