The acid rock reaction experiments were performed by varying acid concentration, reaction temperature and flow velocity.
The operational factors were initial phenol concentration, reaction time, and Cu/TiO2 dosage.
Three main factors, which include catalyst (NaOH) concentration, reaction temperature and time, were varied according to a central composite design.
The biodiesel production process parameters are the alcohol:oil molar ratio, catalyst concentration, reaction temperature and reaction time.
The results showed that the rate of acid reaction can be accelerated by increasing acid concentration, reaction temperature and velocity.
Additionally, effect of enzyme type, enzyme concentration, reaction time and temperature were evaluated subsequently in following experiments.
Three factors KMnO4 concentration, reaction temperature, and reaction duration were tested in a two-level full-factorial design-of-experiment.
The effects of catalyst concentration, reaction time and reaction temperature were investigated in detail.
The catalytic activity was dependent upon ozone concentration, reaction times, and the amount of Mn loading.
The factors studied were: reaction temperature, molar ratio of methanol to oil, catalyst concentration, reaction time and catalyst type (NaOH and KOH).
The effects of different acids (oxalic acid, maleic acid, citric acid and sulfuric acid), acid concentration, reaction temperature and reaction time on the hemicelluloses hydrolysis were investigated.
