A step-change flow rate liquid hot water (SCFLHW) process was developed with the objective of improving the total sugars recovery including xylose and glucose from sweet sorghum bagasse (SSB). Total xylose yield increased from 60% for batch system (4.25% w/v, 18 min, 184 °C) to about...

A kind of solid catalyst of Fe(Ⅱ)–Zn double-metal cyanide (DMC) complexes was prepared through co-reaction of potassium ferrocyanide, zinc chloride and complexing agent of tert-butanol. This catalyst was characterized by using several techniques such as XRD, TG/FT-IR, EA, BET and SEM. And it...

In this study, a pilot scale of 100t/year biodiesel production system, mainly consisting of a fixed-bed and a down-stream plug-flow reactors, was setup to test different feedstock oils, especially a kind of high-acidified oil, trap grease, for their feasibility as biodiesel feedstock in China....

A response surface methodology (RSM) was used to evaluate the effects of pH and microalgal biomass concentration (BC) on alkaline flocculating activity for harvesting one freshwater green algae <i>Scenedesmus quadricauda</i> #507 and one marine diatom <i>Chaetoceros</i> <i>muelleri</i> #862. The pH value and BC were...

Microalgal biofuel research in China has made noticeable progress, and algae cultivation for biofuel production is considered to be an important contribution to <em>Greenhouse Gas</em> (GHG) mitigation and energy security. In this paper, the algal biofuel potentiality in China was reviewed from the...

Detailed review of existing models resulted in the development of a new mathematical model to study biomass gasification in a circulating fluidized bed. Hydrodynamics as well as chemical reaction kinetics were considered to predict the overall performance of a biomass gasification process. The...
