Title: Minoru Yamamoto: Innovator in Petroleum Coke Production

Introduction

Minoru Yamamoto is a notable inventor based in Ichihara, Japan. He has made significant contributions to the field of petroleum coke production, holding a total of 3 patents. His innovative processes have advanced the quality and efficiency of petroleum coke manufacturing.

Latest Patents

Yamamoto's latest patents include a method for producing high-crystalline petroleum coke. This process involves using low-sulfur petroleum feedstock, such as virgin crude oil and distillation residuum. The feedstock undergoes preheat treatment under specific conditions to facilitate cracking and soaking. Following this, the preheat-treated feedstock is subjected to flash distillation to eliminate non-crystalline substances and recover distillate. The distillate is then fractionated to yield a heavy residue, which is further processed through delayed coking to produce high-quality coke with a coefficient of thermal expansion of less than 1.0 × 10⁻⁶ /°C over a temperature range of 100°C to 400°C.

Another significant patent involves a process for producing a petroleum coke of unusually high-crystalline texture and purity. This method includes a preheat-treating step to remove non-crystalline substances and a coking step where heavy oil is coked in a crystallizer. The design allows for the downward flow of pitch-like heavy oil, which accumulates and cokes while discharging gaseous light hydrocarbons from the upper part of the crystallizer. This innovative approach promotes high growth and orientation of coke crystals.
