The interest in Gas-to-Liquid technology (GTL) is growing worldwide because it involves a two-step indirect conversion of natural gas to higher hydrocarbons ranging from Liquefied Petroleum Gas (LPG) paraffin wax. GTL makes possible obtain clean diesel, naphtha, lubes, olefins, and other industrially important organics gas. This article brief review discussing the state-of-the-art GTL, includin...

Sustained increase in plastic use has placed a significant burden on waste disposal infrastructure. Pyrolysis is the process of decomposing high-molecular-weight compounds by heating plastics at 500–1000 °C without oxygen. This considerably reduces greenhouse gas emissions and high alternative energy effect (0.57 TOE ton−1). After separation process, oil produced pyrolysis (C5–C20) can yield na...

Substitution of hazardous substances against less hazardous ones is a central requirement of the European Chemical Regulation REACH (European Regulation 1907/2006/EC). Hazardous substances emitted from products may not only affect the worker; drift off and distribution in the environment may finally result in exposure of the general population. This potential threat to health is covered by the ...

The techno-economic performance and CO2 equivalent (CO2eq) reduction potential of bio-based aromatic production cases with without capture storage (CCS) have been evaluated compared to those fossil-based production. bio-cases include tail gas reactive pyrolysis (TGRP), catalytic (CP), hydrothermal liquefaction (HTL), gasification-methanol-aromatics (GMA), Diels-Alder furan/furfural combined lig...

This paper describes the applicability of a Hg-electroplated-Pt ultramicroelectrode in the quantification of elemental sulphur in naphtha samples by square-wave voltammetry. A reproducible deposition methodology was studied and is reported in this paper. This methodology is innovative and relies on the quality of the mercury stock solution to obtain reproducible surfaces required for the analyt...

The analysis of organic solvents by ICP-MS is challenging due to their high carbon content and volatility. Naphthas are an important class of organic liquids produced in the petrochemical industry, byproducts of the crude-oil refining process. Because they are organic based and have a variety of compositions, naphthas present a special challenge for ICP-MS analysis: the carbon causes polyatomic...

The hydrocracking of high-density polyethylene (HDPE) blended with vacuum gas oil (VGO) has been studied to assess the effect H2 pressure on yield and composition products aim obtaining commercial fuels, mainly naphtha. experiments have performed using a PtPd/HY catalyst in semibatch reactor under following conditions: pressure, 20–110 bar; 440 °C; feed ratio, 0.1 gcat (gfeed)−1; HDPE total 0.2...

Abstract: Hydrogen production via Sorption-Enhanced Chemical-Looping reforming combines hydrocarbons reforming (in this case methane reforming), by chemical-looping auto-thermal reforming, with water-gas shift and carbonation reactions. Both H2 production rate and concentration depend on the chemical equilibrium that is established in the fuel reactor and that is influenced by several parameter...

The first of these chemicals, mineral spirits, is known by a number of different names. Benzine, petroleum spirits, mineral turpentine, naphtha and painters naphtha are just a few of the synonyms of mineral spirits. This solvent is actually a mixture of a number of different hydrocarbons. It is distilled from petroleum and is composed of chemicals having generally five to seven carbons. It repr...
