Catalytic activity of HKUST-1 in the oxidation of trans-ferulic acid to vanillin

Abstract: HKUST-1 was used as a catalyst in the conversion of trans-ferulic acid to vanillin. The generation of unsaturated metal sites within HKUST-1 is the fundamental step in the catalytic process. When activated under vacuum, the catalyst gives complete conversion in only 1 h with a significant average reaction yield of 95%.

Physicochemical Characterization of Spent Caustic from the OXIMER Process and Sour Waters from Mexican Oil Refineries

Abstract: Spent caustic is a waste from oil refineries which is difficult to treat and dispose of due to its noxious properties such as high content in paraffins and asphaltenes hydrocarbons which form all sorts of emulsions and solutions, from 5 to 18% of free NaOH, up to 35 g of Cl-/L, phenol compounds, and organic and inorganic sulfur compounds. Its composition depends on the source of the fuel being desulfurated. This mixture is very reactive and therefore its characterization is difficult and dependent on the way the sample is handled. Samples have to be collected cold from the storage container with no more than 6 h of having been rejected from the process. The sampling container must be sealed and pressure-proof. Part of the sample has to be acidified in situ for certain analysis. The spent caustic from Tula refinery in Mexico has 320 g of COD/L from which 114 come from sulfur organic compounds (3.6 g COD/g of S), 153 from phenolic compounds (phenol 78 g of COD/L) and the rest from other petroleum derivative...

Tula industrial complex (Mexico) emissions of SO 2 and NO 2 during the MCMA 2006 field campaign using a mobile mini-DOAS system

Abstract: . The Mexico City Metropolitan Area (MCMA) has presented severe pollution problems for many years. There are several point and mobile emission sources inside and outside the MCMA which are known to affect air quality in the area. In particular, speculation has risen as to whether the Tula industrial complex, located 60 km northwest of the MCMA has any influence on high SO2 levels occurring on the northern part of the city, in the winter season mainly. As part of the MILAGRO Field Campaign, from 24 March to 17 April 2006, the differential vertical columns of sulfur dioxide (SO2) and nitrogen dioxide (NO2) were measured during plume transects in the neighborhood of the Tula industrial complex using mobile mini-DOAS instruments. Vertical profiles of wind speed and direction obtained from pilot balloons and radiosondes were used to calculate SO2 and NO2 emissions. According to our measurements, calculated average emissions of SO2 and NO2 during the field campaign were 384±103 and 24±7 tons day−1, respectively. The standard deviation of these estimations is due to actual variations in the observed emissions from the refinery and power plant, as well as to the uncertainty in the wind fields at the exact time of the measurements. Reported values in recent inventories were found to be in good agreement with calculated emissions during the field campaign. Our measurements were also found to be in good agreement with simulated plumes.
