Abstract A kinetics study of palm oil methanolysis was conducted at three different temperatures and concentrations catalyst, sodium hydroxide, keeping constant the molar ratio methanol to rotational speed impeller (6:1 400 rpm). The maximum conversion productivity methyl esters were obtained 60 °C 1 wt% NaOH based on oil, they 100 97.6%, respectively. statistical analysis conversions productivities as functions temperature concentration after 80 min reaction, allowed them fit second order...
Phthalates are the most important plasticizers used in polymer industry. However, their fossil origin and results of recent tests showing potential negative effect on human health have encouraged industry to turn toward non‐phthalate plasticizers. At same time, biodiesel produces a surplus glycerol, thus leading scientific community seek new applications for this substance. This paper presents performance eight esters derived from glycerol as poly(vinyl chloride), including evaluate...
The need for incorporating sustainability principles as a design goal rather than constraint has prompted major changes in chemical process and engineering recent decades. In this regard, assessment via economic, environmental, social dimensions, triad referred to the triple bottom line (TBL), is becoming not only an accounting tool but also means re-evaluate of given or product. Nevertheless, inherent complexity by considering TBL gives rise variety challenges that should be addressed at...
Xylose is an abundant bioresource for obtaining diverse chemicals and added-value products. The production of xylose from green alternatives like enzymatic hydrolysis important step in a biorefinery context. This research evaluated the synergism among four classes hydrolytic purified enzymes-endo-1,4-β-xylanase, α-L-arabinofuranosidase, β-xylosidase, α-D-glucuronidase-over glucuronoarabinoxylan (GAX) obtained brewers' spent grain (BSG) after alkaline extraction ethanol precipitation. First,...
The use of hybrid organic/inorganic materials for self-healing concrete is an alternative to minimize the negative environmental impacts cement demand repair and rehabilitate structures design innovative construction practical application in field. However, performance concrete, with additions different chemical natures, like organic, inorganic, biological materials, needs be assessed determine its effect on fresh hardened characteristics workability mechanical resistance. Moreover,...
Abstract A system for the continuous methanolysis of palm oil using a liquid–liquid film reactor (LLFR) was developed and characterized. This is co‐current, constant diameter (0.01 m), custom‐made packed column where mass transfer area between partially miscible methanol‐rich vegetable oil‐rich phases created in non‐dispersive way, without intervention mechanical stirrers or ultrasound devices. An increase contact enhances reaction rate while absence small, dispersed droplets one phase into...
