The objective of this paper is to design a real-time control solution for chemical processes, namely the ethylene reactor, the key-installation in the petrochemical industry. The controller used is lag or lead controller, a simple yet suitable control tool. This article deals with the problem of finding all first order controllers that stabilize a given LTI continuous time or discrete time plan...

The nonwoven industry is one of the most innovative and important branches global fiber products industry. However, use petrochemical-based materials in many leads to severe environmental issues such as generation microplastics. Synthetic material nonwovens currently around 66%. This review covers potential technologies for bio-based products. current relies heavily on synthetic binders fibers....

With the purpose of development high efficiency catalysts for reactions oxidative conversion lower olefins and paraffins into desired products petrochemical industry it has been synthesized by ion exchange method a range metalzeolite on basis synthetic (NaY) natural (pure dealuminated clinoptilolite mordenite) zeolites cations different metals. It established that prepared zeolite NaY shows rel...

Poly(lactic acid) (PLA) is a green alternative to petrochemical commodity plastics, used in packaging, agricultural products, disposable materials, textiles, and automotive composites. It is also approved by regulatory authorities for several biomedical applications. However, for some uses it is required that some of its properties be improved, namely in terms of thermo-mechanical and electrica...

In this study, renewable products with potentially interesting properties and applications were synthesized by functionalizing linseed oil via epoxidation epoxy ring-opening carboxylic acids anhydrides. LDHs (Layered Double Hydroxides), a well-known class of materials used for wide range reactions, are the catalysts in overall advantages facile separation reusability. our different types anhydr...
