Process study and CO2 emission reduction analysis of coal liquefaction residue fluidized bed pyrolysis

Frontiers in Energy Research, 2022
The direct coal liquefaction process usually produces a liquefaction residue of about 30% of its coal feed. The effective utilization of the coal liquefaction residue (CLR), which contains about 80% organic matter, is of great significance for improving ...

Preparation and properties of bio-oil from the antibiotic residue by hydrothermal liquefaction

工程科学学报, 2022
Antibiotic residue, a kind of biomass, is classified as hazardous waste. However, it is considered a good biomass resource because it contains rich organic matter and bacterial protein with a calorific value equivalent to that of low-rank coal.
