Embodiment 1
[0026] A kind of production process of metal oxide load-containing borosilicate phenolic resin-based activated carbon tail gas desulfurizer for hydrogen fluoride production, described production process comprises the following steps:
[0027] (a) Take 100 parts by mass of phenol and 90 parts of 37% formaldehyde solution into the reactor, slowly add 3 parts of ammonia water under stirring, heat and reflux for 5 hours, and let stand to separate and remove water Layer, then decompression distillation removes residual moisture, obtains phenolic resin prepolymer;
[0028] (b) Dissolving the obtained phenolic resin prepolymer in absolute ethanol to prepare a 15% phenolic resin prepolymer ethanol solution;
[0029] (c) Take 200 parts by mass of the 15% phenolic resin prepolymer ethanol solution in step (b), add 10 parts of phenyltriacyloxysilane, 3 parts of terminal hydroxyl groups with a relative molecular weight of 800 After the silicone oil and 2 parts of boric acid are evenly st...
