The upgrading of diesel oil to produce ethylene rich cracking feedstock is an important and promising technical route reduce the ratio gasoline. In present work, a hydrocracking catalyst suitable for selective straight run high-quality at low cost was developed, by optimizing composition support materials, using amorphous silicon aluminum oxide with high mesopore content as main support, modifi...

The demand for biofuels has begun to shift from first-generation second-generation biofuels. One of the already planned in government’s roadmap is renewable diesel hydrotreatment palm oil. By 2040, share projected reach 1.4 million kL per year, contributing 9% biofuel blend program. As world’s largest oil producer and consumer, Indonesia opportunity achieve a circular economy value chain by uti...

This paper reviews major activities outside the United States on human health issues related to chemical mixtures. In Europe an international study group on combination effects has been formed and has started by defining synergism and antagonism. Successful research programs in Europe include the development and application of statistically designed experiments combined with multivariate data a...

Hydrothermal liquefaction (HTL) biocrude is a promising source of energy with potential for co-processing conventional fuels or as drop-in fuel. However, it needs upgrading to reduce heteroatoms (e.g., N, S, O), improve physical properties, stability, and miscibility hydrocarbons. Distillation method that has not been studied extensively using an industry-accepted procedure on large scale. In t...

The article examines the geographical area delimited for production of Divine and specific characteristics physical-geographical conditions Călărași vineyard through prism different methods distillation wine distillates. Technological regimes distilling raw materials organoleptic physico-chemical indices such as: alcohol content, optical density, pH, aldehyde higher content volatile acid are sc...

Comprehensive Two-Dimensional Gas Chromatography for Detailed Characterisation of Petroleum Products — Comprehensive two-dimensional gas chromatography (GC×GC) is a major advance for the detailed characterisation of petroleum products. This technique is based on two orthogonal dimensions of separation achieved by two chromatographic capillary columns of different chemistries and selectivities. ...

All sophisticated methods for direct determination of methanol require advanced instruments and high technical knowledge which preparing them is very expensive in none developed and developing countries. This work reports a simple and efficient qualitative technique for semi determination of methanol content in herbal distillates by a new modified chromotropic acid method. The technique is base...
