The esterification experiments were carried out in a batch reactor with temperature at 95oC. The four parameters were varying as follows; molar ratio of PFAD to methanol from 1:1 to 1:14, reaction time 0.5 to 10 h, an activated carbon loaded with 10, 20 and 30 wt% of ferric sulfate as a solid acid catalyst and quantity of catalyst from 8 to 48 %(wt/wt of PFAD). The optimum condition for this process was observed at 1:12 molar ratio of PFAD to methanol, reaction time 6 h, activated carbon loaded with 20 wt% of ferric sulfate at 40 %(wt/wt of PFAD). The convertion of FFA average was 98.22%.The final FAME product met with the ASTM D6751-02

Crude Palm oils containing a trace amount of acylated sterol glycoside (ASG) was investigated. During the biodiesel production, ASG can be changed into a form of sterol glycoside (SG) by the alkaline catalysts. SG is insoluble in biodiesel and may promote the formation of its aggregates causing the filter plugging problem. The amount of SG in biodiesel was determined by using Gas Chromatography-Flame Ionization Detector (GC-FID). It was found that the major component of precipitant in the tested biodiesel is SG. Based on the experimental results, sodium aluminosilicate can reduce the amount of SG in the tested biodiesel.

The wood–plastic composites (WPCs) were prepared with 40 wt% RWF content using a twin-screw extruder, followed by compression molding. Silane treatment was applied at various concentrations and treatment times to evaluate the effect of treatment conditions on water absorption, mechanical properties, thermal properties, and morphological characterization of WPCs. The results indicated that alkaline–silane treatment of RWF exhibits higher properties in comparison to silane or alkaline only. In addition, silane concentrations significantly affected water absorption, mechanical strength, and hardness, while treatment times remained relatively unaffected by these properties. The best water resistance, mechanical strength, and hardness of WPCs were achieved by alkaline–silane treatment with 5% silane concentration for 2 h, which improved the in...
