“…One of natural sources that can be used to synthesize mesoporous materials is lapindo mud that had occoured since 2006 in Sidoarjo, East Java. The lapindo mudflow sweped up to 180,000 m 3 of mud per day and contained a lot of silica and alumina [26][27] . This shows the potential of lapindo mud as a natural source in synthesizing mesoporous silica alumina.…”

Cobalt, Molybdenum, Co-Mo and Mo-Co catalysts supported on mesoporous silica-alumina (MSA) were synthesized in this work. The MSA and catalysts were characterized by FTIR spectrometer, AAS, TEM, SAA and acidity test (pyridine adsorption). Their catalytic activity were investigated on hydrocracking of α-cellulose pyrolysis oil. The MSA had BET specific surface area of 52.01 m 2 /g, total pore volume of 0.64 cm 3 /g and pore diameter of 3.80 nm based on BJH desorption method. The results showed that hydrocracking of α-cellulose pyrolysis oil using Co/MSA, Mo/MSA, Co-Mo/MSA and Mo-Co/MSA catalysts was selective for acetic acid, 1-hydroxy-2-propanone and 2-furancarboxyldehide production. The highest amount of liquid product was obtained by using Co-Mo/MSA catalyst (82.13 wt.%).

“…By contrast, a nearly continuous uplift of the main active zone is observed at the Ayaz-Akhtarma mud volcano, probably because the eruption (associated with subsidence) occurred after the date of the last interferogram (10 November 2005). The simultaneous presence of subsidence and uplift has been reported during the eruption of LUSI mud volcano [7]. In this case, the subsidence is caused by the removal of mud from the subsurface and by the collapse of the overburden, while the uplift aligns with the Watukosek fault system.…”

Mud volcanism consists in the surface extrusion of gases, saline waters and mud breccias, which produce conical edifices of various sizes with morphology similar to that of magmatic volcanoes. In this work, DInSAR technique has been used to investigate the ground deformation related to the activity of Azerbaijan mud volcanoes during the period October 2003-November 2005. This work focuses on two important deformation events at the Ayaz-Akhtarma and Khara-Zira mud volcanoes. The ground deformations at mud volcanoes are generally originated by fluid pressure and volume variations in the reservoir. The observed deformation pattern is characterized by pre-eruptive inflation that reaches a cumulative value of up to 20 cm at Ayaz-Akhtarma in about two years. Similar pre-eruptive bulging has been observed at magmatic volcanoes, where uplift is typically associated with magma intrusion. We conclude that mud and magmatic volcanoes display some similarities in the behavior of ground deformation during pre-eruptive stages.

“…3). In general, the eruption is accompanied by a clear signal of subsidence due to the discharge of material and release of gas pressure, as occur at the LUSI mud volcano [e.g., 7,8,9] and at magmatic volcanoes [e.g., 25,26]. By contrast, a nearly continuous uplift of the main active zone is observed at the Ayaz-Akhtarma mud volcano, probably because the eruption (associated with subsidence) occurred after the date of the last interferogram (10 November 2005).…”

“…Reference [6] found preliminary indications of deformation in the dataset analyzed. InSAR techniques have also been employed to explore the ground deformation associated with the LUSI mud volcano in Indonesia [7,8,9]. Using similar techniques, the deformation of mud volcanic systems has been analyzed using the differential interferometry (DInSAR) technique [10].…”
