With a notable portfolio that includes five patents, Sheldon has focused on refining the methods for production of formaldehyde and urea, materials crucial to various industrial applications.

Latest Patents

Sheldon’s recent patents reflect his expertise and commitment to advancing chemical production techniques. One of his significant inventions is the "Integrated process for the production of formaldehyde-stabilised urea." This process entails generating a synthesis gas, undergoing a water-gas shift to form a shifted gas, and subsequently recovering carbon dioxide. His method includes synthesizing methanol from the carbon dioxide-depleted synthesis gas and subjecting it to oxidation. The ammonia synthesis from the ammonia gas leads to the reaction of ammonia with a recovered carbon dioxide stream to form a stabilised urea product.

Another of his latest innovations is a "Process for the production of formaldehyde." This invention involves oxidizing methanol with air in a formaldehyde production unit, thereby producing a formaldehyde-containing stream. The process includes separating this stream into usable products while ensuring the vent gas is managed effectively, potentially being redirected to other stages of synthesis gas generation or urea synthesis.
