Title: Wenlong Xu and a High-Pressure Hydrothermal Method for Recovering Useful Products from Manure.

Introduction

Wenlong Xu is an inventor based in Qingdao, China, and works with China University of Petroleum (East China). His patent describes a process for converting livestock and poultry manure into artificial peat and fulvic acid.

Latest Patents

The provided information lists 1 patent for Xu: “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 it and processing it in an electromagnetic heating tube reactor and a tower-type delay reactor. A depressurization flash tower separates the resulting material. Part of the condensate is returned to the concentration-adjusting tank, while a pressure filter separates the solid slurry. The filtered solid is used as artificial peat. The filtrate is heated to at least 380°C, desalted, and combined with the remaining flash condensate to produce fulvic acid.

Career Highlights

Xu’s listed patent focuses on processing livestock and poultry manure into two useful products. The described approach combines high-pressure hydrothermal treatment, separation, heating, and desalination.
