Title: Quan Gan and High-Pressure Hydrothermal Processing of Livestock Manure.

Introduction

Quan Gan is an inventor based in Qingdao, China, and is associated with China University of Petroleum (East China). His patent work addresses the conversion of livestock and poultry manure into useful materials through high-pressure hydrothermal processing.

Latest Patents

The provided information lists 1 patent for Quan Gan: “Method for Preparing Artificial Peat and Fulvic Acid from Livestock and Poultry Manure in Breeding Industry Through High-Pressure Hydrothermal Method.”

The method adjusts manure concentration to 10–40% before pressurizing and processing it in an electromagnetic heating tube reactor and a tower-type delay reactor. A depressurization flash tower separates the resulting material, while part of the flash condensate is returned to the manure concentration-adjusting tank. Pressure filtration separates the solid slurry, and the filtered solid is used as artificial peat. The filtrate is heated to 380°C or above, desalted, and combined with the remaining flash condensate to produce a fulvic acid product.

Career Highlights

Gan’s listed patent focuses on recovering products from livestock and poultry manure. The process describes a sequence of hydrothermal treatment, separation, heating, and desalting intended to yield artificial peat and fulvic acid.
