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

Introduction

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

Latest Patents

The supplied information lists one patent for Qiao: “Method for Preparing Artificial Peat and Fulvic Acid from Livestock and Poultry Manure in Breeding Industry through High-Pressure Hydrothermal Method.” The process adjusts manure concentration to 10–40%, then uses pressurization, electromagnetic heating, and a tower-type delay reactor. After depressurization and separation, the filtered solid is used as artificial peat. The filtrate is heated to at least 380°C and desalted, then combined with flash condensate to produce fulvic acid. The patent record provided identifies 1 patent.

Career Highlights

Qiao’s listed work connects his inventive activity with resource recovery and the processing of agricultural waste. The described method aims to produce two useful materials from livestock and poultry manure through a sequence of heating, separation, and treatment steps.
