摘要

An abbreviated, energy efficient and manipulative process and recipe using a novel binder-combination, to custom-make shaped TS-1 product wherein, their physico-chemical attributes can be engineered, variegated or optimized independent of one another, according to specific stipulations for diverse catalytic reactions that employ them.

主权项

1. A method of making a shaped Titanium Silicalite 1 product comprising the steps of:
i) providing powdered raw Titanium Silicalite 1 material which may or may not have undergone calcination; ii) adding to the Titanium Silicalite 1 material from step (i), a binder composition comprising a combination of one or more Oligomeric silicate and one or more alcohols, and at least one hydrolysing agent; iii) forming the Titanium Silicalite 1 material mixture from step (ii) into a dough; iv) fabricating the dough from step (iii) into a shaped Titanium Silicalite-1 product by means of an operation such as extrusion, pelleting or tableting; v) drying the shaped Titanium Silicalite-1 product from step (iv) at elevated temperature for a pre-determined period of time; wherein the properties of the said shaped Titanium Silicalite 1 product are engineered by regulating one or more of the following, factors or suitable combinations thereof: (i) the amount of hydrolysing agent that is added; (ii) the stage(s) of the reaction when the said hydrolysing agent is added; (iii) the amount of water along with the hydrolyzing agent; (iv) the amount of the binder composition or precursor added; (v) the duration of the operation of mixing of binder composition and hydrolyzing agent; (vi) the drying time and temperature.
