"Adiabatic fixed-bed reactor without temperature gradient" can provide a reactor capable of maintaining the axial temperature of the catalyst bed without gradient, uniform radial reaction, and adjusting the height of the gas distributor according to the amount of catalyst loading. It is suitable for fast reaction and large thermal effect, usually causing overheating and undercooling of the catalyst bed, and gas phase reaction process in which two or more gases participate. It is an adiabatic fixation with an adjustable gas distributor. Bed reactor. "A catalyst for the catalytic partial oxidation of methane to produce synthesis gas and its preparation method" provides a catalyst for the preparation of synthesis gas supported by methane and a preparation method thereof. By adjusting the composition of the catalyst to improve the performance of the catalyst, a supported catalyst with good activity, high selectivity, and stable reaction operation under conditions of large space velocity was prepared.
In response to the shortcomings of the existing technology of methyl isobutyl ketone (MIBK), researchers conducted a large number of experiments to invent a dehydration apparatus for a methyl isobutyl ketone synthesis solution, which consists of a de-acetone/water column body and an intermediate liquid/liquid separator. The condenser, the reboiler, the pump, and the connected pipelines constitute the acetone product collected at the top of the tower and the aqueous phase produced at the intermediate liquid/liquid separator. The tower reactor stream enters the next distillation tower. The method has a simple process, good dewatering effect, and a significant reduction in equipment investment.
Jilin Petrochemical won the national patent for three achievements
On January 12, from the State Intellectual Property Office, it was reported that the three achievements of “a non-temperature gradient adiabatic fixed-bed reactor†declared by the Jilin Petrochemical Research Institute won the national patent and became the proprietary technology of Jilin Petrochemical.
