Title: The Innovations of Donald A. Hickson
Introduction
Donald A. Hickson is a notable inventor based in Benicia, CA (US). He has made significant contributions to the field of chemical engineering, particularly in the area of xylene isomerization and the formation of inorganic agglomerates. With a total of 4 patents to his name, Hickson's work has had a considerable impact on industrial processes.
Latest Patents
Hickson's latest patents include a process for xylene isomerization using a zeolite with a group II metal. This innovative process allows for the isomerization of xylenes containing ethylbenzene to achieve near equilibrium amounts of paraxylene while converting ethylbenzene into hydrocarbons that can be easily removed from the xylenes. The isomerization reaction employs a ZSM-5 type catalyst with an added metal such as zinc, cadmium, or barium, in concentrations ranging from 0.05 to 1.5 percent. This process is conducted in the absence of added hydrogen at low pressure, ideally between 0 and 200 psig, resulting in relatively low xylene losses even at high ethylbenzene conversion levels. Another significant patent involves a process for forming plastic inorganic agglomerates, which can be utilized to create inorganic catalysts or adsorbent bodies.
