Title: The Innovative Contributions of Shigeki Nagamatsu in the Field of Refining Technology
Introduction
Shigeki Nagamatsu, an accomplished inventor based in Yokohama, Japan, has made significant strides in the realm of refining technology. With three patents to his name, he has focused on innovative methods that enhance the production and quality of refined oil and gas oil fractions. His work is particularly relevant in the context of today’s growing emphasis on reducing environmental impacts and improving production efficiency.
Latest Patents
Nagamatsu's latest patents highlight his expertise in refining processes. One of his notable inventions is a method for producing refined oil which achieves a viscosity of 20 cst or lower at 135°C, a pour point of 30°C or lower, and minimizes sulfur content to 0.3 wt % or lower. This process involves bringing feed oil into contact with hydrogen in the presence of specialized catalysts designed for demetalization and desulfurization. The result is a refined oil with significantly lower viscosity and sulfur concentrations, allowing for reduced production costs.
Another substantial patent addresses the desulfurization of gas oil fractions. This method includes a hydrodesulfurization step for a low-boiling gas oil fraction, followed by a separate treatment for a high-boiling fraction. The innovation lies in the integrated approach, using unreacted hydrogen from the second step to assist in the hydrodesulfurization of the first, creating a more efficient overall process.
