This invention discloses a curing process for the upper tobacco leaves of Yunyan 87 based on the synergistic regulation of yellowing and color fixation. The yellowing period is divided into three stages: in the early stage, the temperature is increased at 0.8~1.2℃ / h to 36~38℃ (wet bulb 31~35℃), and the temperature is maintained for 10~14h until the high-temperature layer begins to yellow; in the middle stage, the temperature is increased at 0.8~1.2℃ / 3h to 39~41℃ (wet bulb 35~36℃), and the temperature is maintained for 18~22h until the high-temperature layer is completely yellow and collapses; in the late stage, the temperature is increased at 0.8~1.2℃ / 4h to 41~43℃, and the temperature is maintained for 18~22h. The color-fixing period is divided into three stages: in the early stage, the temperature is raised to 44~46℃ (wet bulb 34~35℃) and stabilized for 3~4 hours until the main vein of the high-temperature layer turns white; in the middle stage, the temperature is raised to 47~49℃ (wet bulb 35~36℃) and stabilized for 16~20 hours until the leaf veins of the low-temperature layer turn white and the leaves turn yellow; in the later stage, the temperature is raised to 53~55℃ (wet bulb 36~37℃) and stabilized for 18~20 hours until the leaf tissue of the low-temperature layer is completely dry. Compared with the existing curing process, this process moderately raises the temperature and humidity during the yellowing stage and moderately reduces the humidity and curing time during the color-fixing stage, so that the tobacco leaves turn yellow fully, promote the rapid degradation of starch and the transformation of aroma components, and avoid the phenomenon of green curing, lees curing and ash hanging on the upper tobacco leaves due to insufficient yellowing and color fixing.

This invention discloses a method for the ethylene glycol hydrolysis of polyethylene terephthalate (PET) with staged control of ethylene glycol dosage. The method includes: in a first stage, adding PET and ethylene glycol to the reaction system at a molar ratio of 1:1 to 1:3, and reacting at 180–196 °C for 0.5–2 h under the action of a solid catalyst; in a second stage, adding ethylene glycol to the reaction system to achieve a molar ratio of ethylene glycol to PET of 1:5 to 1:8, and continuing the reaction for another 2–4 h. By adding ethylene glycol in stages, the conversion degree of oligomers during the reaction is improved, thereby significantly increasing the monomer yield under the same ethylene glycol dosage conditions, reducing oligomer residue, and lowering subsequent separation costs.

This invention discloses a reactor for water-gas shift reaction and its application. The reactor is suitable for water-gas shift reaction processes containing gaseous and liquid reactants. A reaction chamber is set inside a hollow, sealed cylinder formed by the reactor walls. The reaction chamber is a hollow, sealed chamber surrounded by porous material as its wall surface. A gaseous reactant inlet pipe penetrates the reactor wall and extends into the upper part of the reaction chamber, a liquid reactant inlet pipe penetrates the reactor wall and extends into the cylinder, and a reaction product outlet pipe penetrates the reactor wall and extends into the lower part of the reaction chamber. The catalyst for the water-gas shift reaction is packed in the reaction chamber. The water-gas shift reaction can be carried out under near-isothermal conditions. Water in the liquid reactant does not need to be pre-vaporized and is directly fed into the reactor in liquid form, saving the energy consumption required to transport the corresponding amount of water vapor. Simultaneously, a high molar ratio of water to carbon monoxide is maintained within the reactor, promoting complete conversion of carbon monoxide.
