Title: Innovations of Stephen J Hsia
Introduction
Stephen J Hsia is a notable inventor based in Baton Rouge, LA (US). He has made significant contributions to the field of hydrocarbon synthesis, holding a total of 5 patents. His work focuses on improving filtration systems and catalyst life in slurry hydrocarbon processes.
Latest Patents
One of his latest patents is a filtration system for slurry hydrocarbon synthesis processes using both small and large pore filter elements. This method involves separating and filtering solid particles from a hydrocarbon slurry liquid through two or more filter sections. At least one filter section contains filter elements with a mean pore size of less than 10 microns, while another section has filter elements with a mean pore size of 10 microns or greater. The small pore filter effectively excludes smaller catalyst fines produced by catalyst particle attrition, resulting in a liquid product that is substantially free of particulates. The large pore filters allow smaller fines to pass while excluding larger catalyst particles, leading to a liquid product that contains the fines generated from catalyst particle attrition. Another significant patent involves a slurry catalytic hydrocarbon synthesis process that employs a supported cobalt component catalyst. This process achieves a short-term catalyst half-life of more than 10 days by using a syngas feed with less than fifty parts per billion of a combined total amount of HCN and NH3.
