Abstract: A method for preparing titanium-containing molecular sieves include the following steps: irradiating a mixed solution containing a silicon source, a template and a titanium source by a light source containing ultraviolet light before crystallization, and then subjecting the mixed solution to crystallization and post-treatment to obtain the titanium-containing molecular sieve. In the method for preparing titanium-containing molecular sieve of the present invention, the mixed solution containing the silicon source, the template and the titanium source is treated with the ultraviolet light, and free radicals generated by the ultraviolet light can effectively dissociate titanium oligomers and accelerate the hydrolysis of the silicon source, and thus match the hydrolysis rate of a silicon-titanium precursor, thereby preventing a titanium monomer from self-polymerization to form non-framework titanium.

Abstract: A method for preparing titanium-containing molecular sieves include the following steps: irradiating a mixed solution containing a silicon source, a template and a titanium source by a light source containing ultraviolet light before crystallization, and then subjecting the mixed solution to crystallization and post-treatment to obtain the titanium-containing molecular sieve. In the method for preparing titanium-containing molecular sieve of the present invention, the mixed solution containing the silicon source, the template and the titanium source is treated with the ultraviolet light, and free radicals generated by the ultraviolet light can effectively dissociate titanium oligomers and accelerate the hydrolysis of the silicon source, and thus match the hydrolysis rate of a silicon-titanium precursor, thereby preventing a titanium monomer from self-polymerization to form non-framework titanium.

The process comprises (a) contacting a feed comprising the oxygenated hydrocarbon compounds with a fluid catalytic cracking catalyst at elevated temperature to produce a cracked products stream, the feed comprising an amount of sulphur; (b) separating catalyst from the cracked products stream; (c) separating a light fraction from the cracked products stream; and (d) removing hydrogen sulphide from the light fraction by means of an amine treating process. The fluid catalytic cracking process involves the presence or use of water and/or steam and comprises a working-up process of the cracked products stream. In the working-up process, one or more chemical additives for reducing or hindering the formation of foam in amine liquids selected from defoamers and demulsifiers are added to the amine solvent in one or more amine treaters.
