H-Oil gas oils have a higher density and nitrogen content, consequently much lower reactivity than straight-run vacuum during fluid catalytic cracking (FCC). The conversion of observed in laboratory unit at constant operating conditions showed 20 wt.% rate hydrotreated oil. Thus, revamp commercial FCC units, the selection activity catalyst with coke selectivity is needed to provide stable troub...

A combined heat and power (CHP) system, which consists of a proton exchange membrane fuel cell an integrated processor is developed based on solving the energy balance between endothermic exothermic hydrogen production reactions. The system simplifies traditional complex processing, only three reactor units are needed—catalytic combustion, new CO removal. In novel CHP H2-rich reformate from met...

Strongly confined, fully inorganic cesium lead halide perovskite nanocrystals are of great promise for light-emitting devices in the blue spectral range owing to their high photoluminescence quantum yields. A combination broadband fluorescence up-conversion and transient absorption spectroscopies was used study early exciton dynamics quasi-1D CsPbBr3 nanoplatelets (3 × 4 23 nm3, NPls). This all...

The tanning industry generates significant amounts of solid waste and post-production wastewater, which should be managed in accordance with the principles circular economy. Waste is generated at various technological stages production. This comprises mainly leachate. A comprehensive solution to problem disposal this very important from economic environmental points view. work presents research...

Indonesia annually produces significant amounts of biomass waste in the agriculture sector. Rice husk, one highest produced agricultural materials, has sufficient caloric value to produce syngas a gasification system generate sustainable energy. However, production tar from rice husk is significantly high, damaging equipment and internal combustion engine. This study carried out performance ana...

So it can provide inspiration measuring instruments for measurement SO2 Particulates Gas which economic efficient value, so that be used by public levels Sidoarjo Mudflow area. The Android-based system on is an implementation previous developments terms data display visible smartphones accessed remotely or anywhere connected to ...

This study presents a prediction of acacia wood Vietnam gasification in downdraft gasifier based on the thermodynamic equilibrium model. Analytical solution for mathematical model obtained by using an EES (Engineering Equation Solver) program. In survey, moisture content per mole biomass MC= 10 ¸ 30%, The ratio actual amount oxygen used with complete combustion ER= 0.21 0.4. Results indicated t...

CO2 emissions associated with hydrogen production can be reduced replacing steam methane reforming electrolysis using renewable electricity a trade-off of increasing energy consumption, water consumption and cost. In this research, linear programming optimization model system that considers simultaneously cost on cradle-to-gate basis was developed. The used to evaluate the impact intensity opti...

The effects of a mechanical process on the solid fuel quality and anaerobic biodegradability hazelnut olive pruning were determined. feedstock was treated using two-stage dry milling process, followed by fractionation into four different products. coarser products from processing both raw materials, named C M, notable for high reduction in ash nitrogen content. Therefore, hazelnut, they met req...

In this work, the fluid dynamic and thermal behavior of steel was analyzed during argon gas stirring in a 140-t refining ladle. The Eulerian multiphase mathematical model used conjunction with discrete ordinates (DO) radiation steel-slag-argon system. validated by particle image velocimetry (PIV) analysis opening oil layer physical scale model. effect Al2O3 Mg-C as refractory walls studied, Ran...
