  The bitumen industry in the European Union is facing several difficulties, including rising demand, unstable oil supply, rising prices for synthetic polymer modifiers, and a focus on lowering carbon footprint. Bitumen modification with crumb rubber (CR) is one of the most promising solution to these challenges. However, CR-modified bitumen have poor processability and low storage stability. To overcome these flaws we are introducing...

  - INDUSTRIAL CROPS AND PRODUCTS - Year 2017

  In this work, biopolyol obtained from two types of industrial crops’ processing products: crude glycerol and castor oil was used for preparation or rigid polyurethane-polyisocyanurate foams. Bio-based polyol was obtained via crude glycerol polymerization and further condensation of resulting polyglycerol with castor oil. Rigid polyurethane-polyisocyanurate foams were prepared at partial substitution (0–70 wt.%) of petrochemical...

  Wykonano syntezy PUR z oligoeterodiolu, dioli małocząsteczkowych, oleju rycynowego i 4,4´diizocyjanianudicykloheksylometanu. Oznaczono właściwości mechaniczne PUR, kąty zwilżania i napięcie powierzchniowe. Opisano wstępne badania zgodności PUR z ludzką krwią oraz kalcyfikacji powierzchni PUR w warunkach statycznych in vitro. Napięcie powierzchniowe otrzymanych PUR jest zbliżone do napięcia powierzchniowego naturalnych powierzchni...

  - Transactions of the Institute of Fluid-Flow Machinery - Year 2013

  This paper presents an experimental research of helical coil biomass boiler with thermal oil heating agent. Heat exchanger consists of two coaxial helical coils swept by the flue gases. The burner is a single vertical retort connected to the fuel tank (wooden pellets). The boiler is a part of micro-power plant in which the heat from the boiler is exchanged with low-boiling HFE7100 to produce steam for a custom steam turbine. The...

  - Year 2012

  For washing of the oil from polluted soil surfactants solutions were applied. In a research a nonionic synthetic surfactant - polyoxyethylene ether of synthetic fatty alcohol (Rokanol NL6), rhamnolipid biosurfactant JBR 425 (Jeneil Biosurfactant Co. LLC) and their mixtures were used. Results of oil removal from peat soil and sand with mixtures of surfactants solutions at concentration 0,5 g/dm...

  - Environment Protection Engineering - Year 2009

  Zbadano aktywność powierzchniową i właściwości zwilżające surfaktantu niejonowego - Rokanolu NL6, biosurfaktantu - JBR 425 i ich mieszanin. Na podstawie tych badań określono zdolność tych surfaktantów do usuwania oleju syntetycznego (PAO 6) z piasku. Roztwory surfaktantów zostały użyte do przemywania złoża piaskowego w kolumnie oraz odmywania piasku metodą dynamiczną. Testy kolumnowe z roztworami Rokanolu NL6 i JBR 425 dały niskie...
