Lynde Type-A (LTA) zeolite as being molecular sieve and hydrophilic zeolite is used to dehydrate water in the purification of bioethanol. LTA zeolite from LNZ has a small surface area of 29,62 m2/g. Adding HCl activators to LTA Zeolite from LNZ was carrie... see more

In the course of the research, the effect of competing ions (Na+) on multisorption (Cs+, Sr2+) by composite sorbents based on natural and synthetic zeolites under static conditions was studied. It was found that the maximum concentration of competing ions... see more

Red mud is a bauxite industrial waste of reddish-brown mud with high alkalinity. Red mud has relatively high silica and alumina content, so it can be utilized as a raw material in the synthesis of zeolite. This study aims to synthesize high-purity NaP zeo... see more

Natural zeolite (ZA) obtained from Wonosari, Indonesia, was treated with acetic acid (ZAA) or NaOH (ZAB), and the combination of both treatments (ZAAB) in order to increase the Si/Al ratio and catalytic performance on hydrotreatment of castor oil. The Si/... see more

The average productivity of upland rice in Indonesia is around 4.4 tons per ha. This productivity is classified as very low when compared to the potential yield which can reach 8.5 tons per ha. The utilization of synthetic zeolite as soil amendment and li... see more

Environmental and health problems related to water pollution by bacteria are a big challenge in the water treatment process. This pollution is caused by industrial development and increased population growth. Bacterial removal methods in water are continu... see more

Petroleum is still the primary energy used in the world. Its diminishing production is the trigger to find alternative energy to replace it. Biofuel is an alternative energy that has the potential to replace petroleum because it is renewable, environmenta... see more
