Saint-Gobain Ceramics & Plastics, Inc. filed application numbered 10863/DELNP/2013 that is titled PROCESS FOR MANUFACTURING SILICON CARBIDE. This patent application has been granted as Patent Number 316785.
The invention covers chemical compounds. The invention relates to a process for the production of carbon monoxide in the production of carbon monoxide, a process for the production of carbon dioxide. and a source of silicon having a purity of greater than 95% of SiO 2 , at a temperature above 1500 ° C., to the simplified reaction: SiO 2 + 3C = SiC + 2CO (1), said process being characterized in that said carbon-based source first undergoes a treatment for removing the contained hydrogen, in such a way that the elemental hydrogen content (TEMH) thereof is less than 2% by weight.
During patent examination, the patent examiner raised objections under Section 3(d) of the Indian Patents Act, wherein the examiner stated that the Claims 1 to 14 fall u/s 3(d) of the Patents (Amended) Act, 2005 as the said claims define the mere use of a known process.
As a response to said objection, the applicant responded by submitting that none of these cited references discloses the pre-treatments of the raw materials (petroleum coke, and silica), and does not disclose the requirement that silica is having a purity of greater and the petroleum coke containing an elemental hydrogen content (EHWC) is lesser in weight. According to the present invention, it leads to the reduction in the emissions of polluting gases.
