He holds three patents that showcase his innovative approaches to ammonia production and sulfur fuel technology. His work reflects a commitment to advancing industrial processes and improving efficiency.

Latest Patents

One of Ashok D Rao's latest patents is a process for making ammonia from heterogeneous feedstock. This innovative method involves partially oxidizing a carbon-containing heterogeneous feedstock at low pressure to generate a synthesis gas containing carbon monoxide. The synthesis gas is then isothermally shifted with steam to form hydrogen. Following this, portions of carbon dioxide and argon are cryogenically removed from the shifted gas. The hydrogen is purified using a pressure swing adsorber, and then mixed with high purity nitrogen to convert it into ammonia. The tail stream from the pressure swing adsorber can be recycled for control purposes or used as boiler fuel. This process allows for the recovery of ammonia contained in the purge gas stream through cryogenic condensing.

Another notable patent is for a pelletized fixed sulfur fuel. This fuel is produced by proportioning sulfur-bearing coal and limestone in specific amounts to facilitate a reaction between calcium in the limestone and sulfur in the coal. The mixture is ground, blended, and then formed into pellets. Using a carbonizing or pyrolyzing technique in a traveling grate machine, the pellets are heated to at least 800°F, resulting in the pyrolysis or carbonization of the coal, calcination of the limestone, and fixation of sulfur in a stable calcium compound that remains in the ash after combustion.
