The paper deals with the corrosion behavior of stainless steels as candidate materials for biofuel production plants by liquefaction process of the sorted organic fraction of municipal solid waste. Corrosion tests were carried out on AISI 316L and AISI 304L stainless steels at 250 °C in a batch reactor during conversion of raw material to bio-oil (biofuel precursor), by exposing specimens eithe...

Most studies neglect the presence of thermal cracking reactions in industrial FCC process. Nevertheless, the present work proposes a new model which modified the 10-lumps kinetic model given by Jacob el al. (1976), through to inclusion a new lump named dry gas represent the results of the thermal reactions. Similarly as in the 10-lumps kinetic model, the proposed 11-lumps kinetic model consider...

try (HPI), cracking is the process whereby complex organic molecules (e.g.heavy hydrocarbons) are broken down into simpler molecules by the breaking of carbon-carbon bonds in the base material. The rate of cracking and the nature of end products strongly depend on the temperature and presence of any catalysts. Process automation equipment including gas analysis instrumentation contributes essen...

Recently, the API X100 steel has emerged as an important pipeline material for transportation of crude oil and natural gas. At the same time, the presence of significant amounts of hydrogen sulfide (H2S) in natural gas and crude oil cause pipeline materials to corrode, which affects their integrity. In this study, the effect of H2S concentration on the corrosion behavior of API X100 in 3.5% NaC...

Petroleum refineries utilize thermal cracking, catalytic cracking and hydrogenation processes to produce high quality oil products. Hydrodesulfurization is one of the most important methods to remove sulfur from petroleum fractions. Heavy oil contains various types of sulfur compound. The structure of the sulfur compounds affects the ease of sulfur removal1). Acyclic sulfur compounds including ...

The exponential increase of plastic production produces 100 million tonnes of waste plastics annually which could be converted into hydrocarbon fuels in a thermal cracking process called pyrolysis. In this research work, a direct current (DC) thermal plasma circuit is designed and used for conversion of low density polyethylene (LDPE) into diesel oil in a laboratory scale pyrolysis reactor. The...

The oil expulsion efficiency and retention of shale affect the enrichment preservation oil. Two series semi-closed hydrous pyrolysis experiments were performed under in situ geological conditions on a Paleogene sample as comparable analog to evaluate generation potential Funing Formation Subei Basin. results show that 1) oil-generation capacity evolution different lithological combination sourc...
