Abstract

One type of hazardous industrial waste is phenol. The photocatalysis process has become the choice for the treatment of phenol waste. Titanium dioxide or titania (TiO2) is a photocatalyst material that is often used. Carbon nanotubes (CNT) are known to be used to improve the performance of TiO2 photocatalyst material. The CNT used was modified with CTAB (Cetyltrimethylammonium bromide) surfactant. The purpose of this research are to determine the effect of temperature degradation on the performance of the Titania-CNT (CTAB) composites in degrading phenols through the process of photocatalysis. The study began with surface modification of CNT using CTAB surfactant. Then the modified CNT was compiled with TiO2. Then Titania-CNT (CTAB) composite performance in degradating phenol was tested using a variation of the degradation temperature of 40oC and 50oC. The results of this research indicate that as the temperature increases, the phenol which can be degraded by the Titania-CNT (CTAB) composite is also increasing. The highest effectiveness of composite TitaniaCNT (CTAB) performance was obtained when the degradation temperature of 50oC was 99.54%. Keywords : phenol, photocatalysis, composites, TiO2, CNT, CTAB

Abstract

The Kraft pulping process has become the most widely used pulping process in the papermaking industry since its discovery in 1879.This process has three main advantages over other pulping processes, namely the resulting fiber is stronger, can be applied to all wood species. Both softwood and hardwood, and lower operating costs due to the chemical can be reprocessed at a high efficiency of around 97%. One of the units in chemical reprocessing is a plant that aims to produce white liquid (WL) from green liquid (GL) which is then used as a medium for cooking chips in the Digester. This study aims to study temperature variations in the I-V slaker unit at PT. RAPP on the total active alkali (TAA) variation of WL in WL tanks. The temperature of each slaker was correlated with TAA WL using a linear regression approach and was re-tested by comparing the causticizing efficiency in each slaker. To get the optimal operational process in each slaker for the variation of TTA GL and temperature in the slaker, the multiple regression method approach was used. The TAA WL prediction results from multiple regression between TTA and temperature in the slaker were then compared with the TAA WL obtained in the laboratory and it was found that the two values were very close. So this method can be used to determine the optimal operation for variations in TTA GL and temperature in the slaker. If the variation of TAA WL is very small, the proportion of alkaline charge used in the digester can be so that the operational costs can be drawn.

Abstract

The sodium lignosulfonate (SLS) is a derivative compound from lignin which has various usefulness. Commercial SLS is a by-product of Arbiso pulping sulfite industry, but nowadays, the amount of available commercial SLS is scare due to the expensive price of SLS. Therefore, it is needed to find the solution to produce of SLS using a feasible process. This research involves producing SLS by directly cooking the palm oil stem biomass dust in a pressurized reactor using sodium bi-sulfite (NaHSO3) solvent. The experiment focused on the modeling, influence of process variables and its optimization that statistically analyze using the Response Surface Method-Central Composite Design (RSM-CCD). The result showed that the solid-liquid ratio is the most affecting factor to the SLS rendemen. The relation between rendemen and temperature (T), pH (C) and solid-liquid ratio (R) can be modeled as % rendemen = 12.18 + 0.52T – 0.48C + 3.5R – 1.02T2 – C2 – 1.53R2. The optimal operation conditions were identified at temperature of 153.8oC, pH = 4.64 and solid-liquid ratio of 1:15.9.
