Hydrothermal liquefaction (HTL) of barley straw with K2CO3 at different temperatures (280–400°C) was conducted and compared to optimize its process conditions; the aqueous phase as a co-product from this process was recycled to explore the feasibility of implementing wastewater reuse for...

This article reviews the hydrothermal liquefaction of biomass with the aim of describing the current status of the technology. Hydrothermal liquefaction is a medium-temperature, high-pressure thermochemical process, which produces a liquid product, often called bio-oil or bi-crude. During the...

Grate-firing is one of the main technologies currently used for biomass combustion for heat and power production. However, grate-firing is yet to be further developed, towards a better technology for biomass combustion, particularly towards higher efficiency, lower emissions, and better...

Anaerobic digestion is an important approach to treat and utilize kitchen waste, while its biogas residue (BR) disposal remains a serious problem. This study investigated the feasibility of chemical looping gasification (CLG) as an efficient way to treat and generate syngas from BR. Besides,...

Bio-oil is a promising carbon neutral and sustainable alternative for liquid fossil fuels, but the difficulties in property characterization is hindering its further development. Accordingly, this study proposed a fast characterization method of bio-oil via combination of attenuated total...

A small-scale pilot project was built for the pavement-solar energy utilization in this paper. An automatic data acquisition system was designed to measure the effectiveness of the pavement solar energy system based on the operation data of 24h a day in both summer and winter. Through 69days...

Micro-algae have been recognized as a promising feedstock for biofuel production. Effective combining microalgae cultivation with wastewater treatment can reduce CO2 emissions and the cost of microalgae biofuel production, making it more feasible. However, the biomass and lipid productivity must...

In present study, we investigated jet fuel production process, including the crude oil-based conventional process, unconventional oil sources-based process, Fischer–Tropsch synthesis (F–T) process and renewable jet fuel process and analyzed the details of each jet fuel production process....
