Latest Patents

Among his most notable patents are the following:

1. **Chemical Vapor Deposition Reactor and Process**: This invention involves a reactor featuring a heated liner designed for the production of silicon via chemical vapor deposition (CVD). It includes an innovative means for supplying a gas stream within the turbulent flow region. The method allows for the deposition of silicon on a non-reactive substrate, with the option for the liner to be removable for easy separation of the deposited metal. Importantly, the temperature of the liner can be increased above the melting point of the deposited metal for effective recovery.

2. **Process for the Purification of Citric Acid**: In this patent, Lawrence discloses a method for producing citric acid and its salts by reacting acetone dicarboxyl ions, cyanide ions, and alkali metal ions. This process leads to the formation of a citric acid salt, which can be efficiently recovered through precipitation without the formation of calcium salts. The recovered salt offers versatility as it can either be used directly or undergo additional purification before conversion back to citric acid or other derivatives.
