Study on two-step hydrothermal liquefaction of macroalgae for improving bio-oil.

Bioresource Technology, 2020
In this work, the conversion of Enteromorpha clathrata into bio-oil through hydrothermal liquefaction (HTL) was investigated under different preparation conditions. A two-step reaction method was compared with single-step reaction. At a high temperature,

Liquefaction

2022
Abstract To eliminate much of the hardware and many of the processing steps involved in indirect liquefaction, an alternative is to add hydrogen directly to coal, intending to make liquids in one step. Direct liquefaction is simpler in concept, but still involves high temperatures and pressures and the need to convert the primary liquid ...

Application of fuzzy logic to fault tree and event tree analysis of the risk for cargo liquefaction on board ship

, 2020
Risk analysis is of paramount importance in maritime transportation due to the nature of work. The IMO (International Maritime Organization) adopted FSA (Formal Safety Assessment) as guidance to address risk analysis on-board ship.

A review of recent developments of pre-treatment technologies and hydrothermal liquefaction of microalgae for bio-crude oil production

Renewable & Sustainable Energy Reviews, 2019
Microalgae have been widely considered as the potential sources for bio-fuel production without affecting the environment. Hydrothermal liquefaction (HTL) is a suitable technology for converting high water-containing feedstocks (e.g., microalgae) to ...
