This article describes the study of synthesis ZSM-5 Zeolite based on kaolin as catalysts for catalytic cracking heavy distillate

A nonlinear geometric observer is developed, which infers the distillate and residue compositions in a highly-nonlinear binary distillation column from temperature measurements. The estimator performance is evaluated by imposing severe step changes to the input variables. In particular, the capability of the observer reconstruction is assessed with regard to ill-conditioning of the observabilit...

In this work, new correlations are proposed to predict the products yield of delayed coking as a function of CCR and temperature based on the experimental results. For this purpose, selected Iranian vacuum residues with Conradson carbon residue (CCR) values between 13.40-22.19 wt.% were heated at a 10 °C/min heating rate and thermally cracked in a temperature range of 400-500 °C in a laboratory...

In this article, the improved space-time conservation element and solution element (CESE) method are used to simulate the dynamic treatment of the hydrocracking reactor. The dynamic model consists of four lumps: vacuum gas oil (VGO), middle distillate, naphtha, and gas which is dissolved by this method. The offered method can solve the partial differential equations caused by the reactions insi...

Despite their low electrical efficiencies, PVs are widely used to generate electricity from abundant solar energy. In order maximize the utilization of incident energy, PVT collectors have been simultaneously and thermal Furthermore, combining PVTs with humidification-dehumidification (HDH) cycles can provide potable water in remote, arid rural areas that not connected grid. this paper, a PVT-a...
