Introduction

Tetsuo Wada is a notable inventor based in Oomuta, Japan. He has made significant contributions to the fields of petroleum processing and coal treatment. With a total of three patents to his name, Wada's work focuses on improving methods for handling heavy petroleum oil and water-containing coal.

Latest Patents

Wada's latest patents include a method for continuous thermal cracking of heavy petroleum oil. This innovative method allows for a high degree of cracking in a compact reactor, producing residual pitch rich in beta-resin components. The process involves charging preheated heavy oil into an upright cylindrical continuous reactor, which is divided into upper and lower reaction zones. The resultant cracked gas and oil vapor are drawn from the upper reaction zone, while residual pitch is discharged from the bottom of the lower reaction zone. Additionally, Wada has developed improvements to this method, including the incorporation of a cooling chamber and a defoaming chamber to enhance the efficiency of the reaction.

Another significant patent addresses the treatment of water-containing coal. This process involves mixing the coal with a hydrocarbon oil at elevated temperatures and pressures, allowing for the separation of water from the coal. The resulting mixture forms distinct layers, facilitating the extraction of dehydrated coal.
