Reuse of spent bleaching earth by polymerisation of residual organics.
Spent bleaching earth (SBE) is a waste generated by the edible oil industry that currently has limited options for beneficial reuse. In excess of ∼2 million tonnes per year of SBE is generated world-wide with major quantities available in the middle-east where significant volumes of edible oils are produced. Low pressure compaction followed by heat treatment at 150°C causes polymerisation of th...
متن کاملCatalytic Conversion of Acetone to Monoaromatic Chemicals using HZSM-5
The effects of process variables (temperature, space velocity, water addition and Si/Al ratio) on the conversion of acetone to aromatic chemicals have been investigated. The reaction is carried out by fixed bed reactor at an atmospheric pressure to examine the activity and selectivity of HZSM-5. The results show that HZSM-5 exhibited a high active and a shape-selective catalyst for the formatio...
متن کاملThe catalytic cracking of hydrocarbons: paraffins in the HZSM-5 zeolite.
An elementary reaction during cracking of a hydrocarbon in a nanoporous silicalite catalyst includes ejection of a hydrid ion as shown in the picture. The reaction was simulated by means of quantum molecular dynamics.
متن کاملHigh Selectively Catalytic Conversion of Lignin-Based Phenols into para-/m-Xylene over Pt/HZSM-5
High selectively catalytic conversion of lignin-based phenols (m-cresol, p-cresol, and guaiacol) into para-/m-xylene was performed over Pt/HZSM-5 through hydrodeoxygenation and in situ methylation with methanol. It is found that the p-/m-xylene selectivity is uniformly higher than 21%, and even increase up to 33.5% for m-cresol (with phenols/methanol molar ratio of 1/8). The improved p-/m-xylen...
متن کاملNon-oxidative conversion of methane to aromatics over modified zeolite catalysts by transitional metals
The activity of different transitional metals over modified H-ZSM-5 catalysts for methane conversion to aromatics was compared. The first group of catalysts was Mo-impregnated H-ZSM-5 zeolites with 1, 3 and 6 wt% of Mo. The second group was M(3 wt%)- impregnated H-ZSM-5 (M: Ag, Cd, Cr, Mo, Zn and Mn). The catalytic activity of the first group was investigated at 600, 700 and 800 °C and gas hour...
