Embodiment 1

[0021] In the 5L butene hydration four-stage reaction device, the evaluation test was carried out using the DNW-II temperature-resistant resin catalyst produced by Dandong Mingzhu Special Resin Co., Ltd. The amount of catalyst loaded is 1.08L, and the amount of catalyst loaded in each catalyst bed is 270ml. The reactor is divided into four sections. The diameter is Φ2mm, and the bulk density is 3500Kg / m 3 Inert alumina ceramic balls, the ratio of the loading amount of the inert alumina ceramic balls to the catalyst is 1:10, and then the catalyst is loaded. The second, third, and fourth sections use the same method as the first section to load the catalysts of each section into the reactor.

[0022] After the reactor is installed, the airtightness test with nitrogen gas is qualified, and the pressure of the reaction device is adjusted to 8.0MPa, and the water pump is turned on to raise the temperature at the same time. When the reaction temperature rises to 150°C, adjust the ...

Abstract

The invention discloses a filling method of a hydrated resin catalyst, and more particularly relates to the filling method of the butene hydrated resin catalyst, and the filling method is especially applicable to the segmental filling fixed bed hydration process of the butene hydration. The method of the invention is that: inert fillers without the influence on the reaction are arranged at the bottom parts of each catalyst bed layer of a reactor. Compared with the prior filling method, the filling method can effectively reduce the pressure drop of the bed layers of the reactor, avoid the damage of the catalyst and prolong the service life of the catalyst.

Description

technical field [0001] The invention discloses a filling method of a hydration resin catalyst, in particular a filling method of a butene hydration resin catalyst, and the filling method is especially suitable for a staged filling fixed-bed butene hydration process. Background technique [0002] Methyl ethyl ketone is an important low-boiling point solvent, which has excellent solubility and drying properties, can form azeotropes with many solvents, and has a strong effect on many substances, such as resins, fiber derivatives, synthetic rubber, oils, and higher fatty acids. Solvent ability, good solvent for polymer compounds such as nitrocellulose, polyurethane, vinyl resin, acrylic resin, alkyd resin, phenolic resin, adhesive, ink, magnetic tape, pharmaceutical production and lubricating oil dewaxing, widely used in lubricating oil Dewaxing, coatings, adhesives, inks, tapes, medicine and electronic components and other fields. In addition, as an important organic chemical ...
